Nothing ruins a solid gym session faster than underwear that rides up, bunches, or leaves you raw between the thighs. If you’ve ever cut a run short or shifted awkwardly mid-squat because of chafing, you already know that what you wear underneath matters just as much as your training gear.
Finding the best workout underwear for men comes down to a few non-negotiables: moisture management, breathability, support, and a design that actually stays put when you move. The wrong pair can turn a 45-minute workout into an uncomfortable countdown. The right pair? You forget you’re even wearing them.
At SLY Collective, we’ve spent years perfecting underwear that eliminates chafing through our built-in ball pouch design, so we know exactly what separates mediocre workout underwear from the stuff that genuinely performs. We’ve used that expertise to evaluate and compare 12 of the top options available in Australia for 2026.
Whether you’re lifting, running, cycling, or just need something that won’t let you down during a sweaty commute, this guide breaks down the best choices by fabric, fit, features, and value. Let’s get into it.
1. SLY Collective bamboo boxer briefs
SLY Collective’s bamboo boxer briefs earn the top spot because they’re built specifically to solve the chafing problem that most blokes face during workouts. The standout feature is the built-in ball pouch, which physically separates your anatomy from your thighs, eliminating the skin-on-skin contact that causes raw patches and discomfort. You’re not just getting standard athletic fabric here; you’re getting Australian-designed underwear with a longer leg cut that stays in place during burpees, sprints, and heavy squats. The bamboo fabric is naturally breathable and regulates temperature better than synthetic blends, which matters when you’re pushing hard through a sweaty session or training in Australia’s heat.
Sweat and breathability
Bamboo fabric handles moisture differently than cotton or polyester. The material wicks sweat away from your skin while allowing air to circulate, so you’re not sitting in damp underwear halfway through your workout. Bamboo’s natural structure creates micro-gaps in the fibres that trap less heat and let moisture evaporate faster than traditional cotton. This temperature regulation isn’t just about comfort; it keeps your core temperature lower and prevents the clammy feeling that distracts you mid-set. You’ll notice the difference during high-intensity interval training or long runs where ventilation matters most.
Bamboo’s natural breathability and moisture-wicking properties make it one of the most effective fabrics for controlling sweat during intense workouts.
Support and chafe control
The built-in pouch design is where SLY Collective separates itself from standard boxer briefs. Instead of letting everything compress against your thighs, the pouch creates a dedicated compartment that lifts and supports while keeping skin surfaces apart. Chafing happens when friction meets moisture, and this design eliminates both by preventing contact and improving airflow. The longer 15cm leg means the fabric doesn’t ride up during movement, so you’re not constantly adjusting or dealing with bunching around your thighs. Urologists recommend pouch underwear for post-procedure support and general testicular health, which tells you this isn’t just marketing talk. The design provides structured support without compression, so you get stability without feeling restricted.
Price and availability in Australia
SLY Collective boxer briefs retail at $29.95 per pair or you can grab a 3-pack for $99, which works out better if you’re replacing multiple pairs. You can order directly from their Australian website with free shipping on orders over $100, so buying a 3-pack qualifies automatically. They offer free size exchanges if you need to adjust, plus a Comfort Guarantee that covers full refunds on your first pair if they don’t work for you. Orders ship from within Australia, so you’re not waiting weeks for international delivery or dealing with customs. The combination of the no-questions-asked guarantee and direct-to-consumer pricing makes these competitive with premium brands that charge similar amounts but don’t offer the same pouch technology.
2. Under Armour Tech Boxerjock 6-inch
Under Armour’s Tech Boxerjock 6-inch sits comfortably in the best workout underwear for men category because of its reliable performance across different training styles. The HeatGear fabric uses a four-way stretch construction that moves with your body during dynamic movements like box jumps, lateral lunges, or agility drills. Under Armour designed this option specifically for athletes who need consistent moisture control without the bulk of compression gear. The 6-inch inseam provides enough coverage to prevent ride-up while keeping things light enough that you don’t feel weighed down. You’re getting a mid-range option that handles the basics well without trying to reinvent the wheel.
Sweat and breathability
HeatGear fabric is Under Armour’s proprietary moisture-wicking synthetic blend that pulls sweat away from your skin and spreads it across the fabric surface for faster evaporation. The material dries noticeably faster than cotton, which matters when you’re doing multiple training sessions in a day or need to pack gym gear in a bag afterwards. Under Armour added mesh ventilation panels along the inner thighs and waistband to increase airflow where heat builds up most. The four-way stretch means the fabric doesn’t trap heat in one spot because it flexes with your movement instead of staying rigid against your skin.
Support and chafe control
The Tech Boxerjock uses flat-lock seams positioned away from high-friction zones, which reduces the rubbing that causes raw spots during running or cycling. Under Armour’s anti-odour technology treats the fabric to prevent bacterial growth, so the underwear stays fresher longer between washes. The fit sits close to your body without compression, giving you enough support to keep everything stable during explosive movements while allowing natural range of motion. The waistband uses a wide elastic band that distributes pressure evenly, so you’re not dealing with a thin strip that digs in or rolls over.
Under Armour’s flat-lock seam construction eliminates the pressure points that cause chafing during repetitive athletic movements.
Price and availability in Australia
You can find Tech Boxerjock 6-inch boxer briefs at Rebel Sport, The Iconic, and Amazon Australia for around $30 to $35 per pair, depending on sales and colour options. Under Armour runs multi-buy deals fairly regularly, where you can grab 3 or 4 pairs at a discount that brings the per-unit cost down. Most Australian retailers offer free returns within 30 days, so you can test the fit without committing fully. Delivery times from local stockists typically run 3 to 5 business days for metro areas, faster than waiting on international orders from Under Armour’s US site.
3. Saxx Kinetic
Saxx Kinetic boxer briefs bring patented BallPark Pouch technology to the workout underwear category, positioning themselves as a direct competitor in the best workout underwear for men conversation. The brand built its reputation around the pouch concept, using a three-dimensional hammock design that supports without compression while keeping everything separated during movement. Saxx uses a nine-panel construction that follows your body’s natural contours rather than forcing everything into a standard flat pattern. The Kinetic model specifically targets high-output training with its moisture-wicking mesh fabric and friction-free seam placement. You’re paying for engineering that focuses on eliminating the contact points where chafing starts.
Sweat and breathability
Saxx uses a moisture-wicking synthetic blend with strategically placed mesh panels across the pouch and inner thighs to create airflow channels where heat accumulates during intense training. The fabric pulls sweat away from your skin quickly, which prevents the damp environment that leads to irritation and bacterial growth. Saxx integrated breathable mesh gussets into the design to increase ventilation without sacrificing durability in high-wear areas. The material dries faster than traditional cotton or bamboo options, making these suitable for back-to-back training sessions or situations where you need to pack sweaty gear straight into a gym bag.
Saxx’s mesh panel placement creates targeted ventilation zones that address the specific areas where heat and moisture build up during athletic activity.
Support and chafe control
The BallPark Pouch uses a hammock-style construction that cradles and lifts while preventing skin-on-skin contact between your anatomy and thighs. Saxx positions all seams away from friction zones, using flat-lock stitching that sits flush against your skin instead of creating raised ridges. The nine-panel design means the fabric moves independently with your legs and torso rather than pulling in different directions, which reduces bunching and ride-up during squats, lunges, or running strides. You get structured support that keeps everything stable without the restrictive feeling of compression shorts.
Price and availability in Australia
Saxx Kinetic boxer briefs retail between $40 and $50 per pair at Australian stockists including David Jones, The Iconic, and Rebel Sport. Most retailers stock multiple colours and run sales throughout the year that can bring prices down to the $30 range. You’ll find free shipping on orders over $50 from most online retailers, and return policies typically cover 30 days for unworn items. Delivery from Australian stockists takes 3 to 7 business days depending on your location.
4. Lululemon Always in Motion Boxer
Lululemon’s Always in Motion Boxer brings the brand’s premium athletic fabric technology to the workout underwear category with a focus on unrestricted movement and sweat management. The design uses Seamless construction across high-friction zones and a four-way stretch fabric that adapts to your body during complex movement patterns like Olympic lifts, yoga flows, or sprint intervals. Lululemon engineered this option for blokes who need underwear that performs as well as their other training gear, using the same moisture-wicking technology found in their best-selling training shorts. The boxer sits at a 5-inch inseam that provides coverage without excess fabric bunching around your thighs during deep squats or lunges.
Sweat and breathability
Lululemon’s proprietary fabric blend combines nylon and Lycra in a construction that pulls moisture away from your skin while maintaining airflow through the material. The Always in Motion Boxer uses zoned mesh ventilation strategically placed along the inner thighs and lower back where your body generates the most heat during training. You get faster drying times compared to cotton options because the synthetic blend doesn’t hold water in the fibres. The seamless design eliminates the thick overlapping fabric sections that trap heat and moisture against your skin, creating a lighter overall feel that works well for high-intensity training sessions or warm-weather workouts.
Support and chafe control
The seamless construction removes the friction points where traditional seams rub against your skin during repetitive movements. Lululemon uses a contoured pouch design that provides support without compression, keeping everything stable during explosive exercises while allowing natural movement. The four-way stretch fabric moves independently with your legs and torso rather than pulling in opposite directions, which reduces ride-up and bunching. The wide waistband distributes pressure evenly and includes silicone grip strips on the interior to prevent rolling or slipping during intense activity.
Lululemon’s seamless construction and four-way stretch create a friction-free environment that eliminates the pressure points responsible for chafing during athletic movements.
Price and availability in Australia
You’ll find the Always in Motion Boxer at Lululemon stores across Sydney, Melbourne, and Brisbane, plus their Australian website at $38 per pair. Lululemon offers free shipping on orders over $75 and provides a quality guarantee that covers manufacturing defects. Their return policy allows 30 days for unworn items with original tags attached. Delivery from their Australian warehouse typically takes 3 to 5 business days to metro areas.
5. Nike Dri-FIT boxer briefs
Nike Dri-FIT boxer briefs earn their place among the best workout underwear for men through proven performance across multiple training environments and the brand’s decades of experience in moisture management technology. The Dri-FIT fabric system uses a polyester-spandex blend engineered specifically to move sweat away from your skin and towards the fabric surface where it evaporates quickly. Nike positioned this option as a reliable everyday training choice that handles everything from gym sessions to outdoor runs without the premium price tag of specialised athletic underwear. You’re getting a contoured fit that follows your body’s natural shape while maintaining enough room for unrestricted movement during exercises that require full range of motion.
Sweat and breathability
Dri-FIT technology pulls moisture through the fabric fibres using hydrophobic polyester that repels water rather than absorbing it like cotton does. Nike engineered the material to spread sweat across a larger surface area, which accelerates evaporation and keeps you drier during sustained cardio or high-intensity interval training. The four-way stretch construction prevents the fabric from restricting airflow when it stretches during movement, maintaining breathability even when the material is pulled tight against your skin. You’ll notice the boxer briefs dry faster between sets or during active recovery periods compared to natural fibre options.
Nike’s Dri-FIT polyester blend moves moisture away from your skin three times faster than traditional cotton fabrics.
Support and chafe control
Nike uses a supportive pouch design that provides structure without compression, keeping everything stable during jumping movements, sprints, or directional changes. The brand positions flat seams along the inner thigh and waistband to reduce friction points where skin rubs against fabric or other skin surfaces during repetitive motion. You get a snug fit that prevents excess fabric from bunching or riding up while still allowing natural movement patterns. The elastic waistband sits flat against your lower abdomen without digging in or creating pressure points during core exercises.
Price and availability in Australia
Nike Dri-FIT boxer briefs retail between $25 and $35 per pair at Australian stockists including Rebel Sport, The Iconic, and Nike’s Australian website. Most retailers offer multi-pack options that reduce the per-unit cost when you buy three or more pairs at once. You’ll find free shipping on orders over $50 from most online retailers, with delivery taking 3 to 5 business days to metro areas. Nike stores across major Australian cities stock these year-round, and seasonal sales typically bring prices down by 20 to 30 per cent.
6. Adidas Sport Performance boxer briefs
Adidas Sport Performance boxer briefs deliver reliable moisture control and a contoured fit that makes them a solid choice for blokes who want dependable training underwear without specialty features or premium pricing. The brand uses its Climalite fabric technology to handle sweat during workouts while maintaining a streamlined design that works across different training styles. You’re getting a 6-inch inseam that provides adequate coverage without excess material bunching around your thighs during squats or leg work. Adidas positions these as an everyday training option that handles the fundamentals well, making them suitable for gym sessions, running, or general athletic activity where you need underwear that simply performs without drawing attention to itself.
Sweat and breathability
Climalite fabric pulls moisture away from your skin using polyester fibres engineered for rapid evaporation, which keeps you drier during sustained cardio or circuit training. Adidas incorporates mesh ventilation panels along the inner thighs and back where your body generates the most heat during movement. The synthetic blend dries faster than cotton options, making these practical for situations where you’re packing gym gear immediately after training or doing multiple sessions throughout the day. You’ll find the material maintains its shape and performance characteristics even after repeated washes, which matters when you’re cycling through training gear regularly.
Adidas Climalite technology manages moisture through engineered polyester fibres that accelerate sweat evaporation during athletic activity.

Most retailers stock multi-pack options that reduce the per-unit cost when buying three or more pairs together. Delivery from Australian stockists typically takes 3 to 5 business days to metro areas, with free shipping available on orders over $50 from most online retailers.
7. 2XU compression shorts
2XU compression shorts take a different approach to the best workout underwear for men by prioritising graduated compression technology over traditional boxer brief design. The brand engineered these specifically for high-intensity training where muscle support and recovery matter as much as chafing prevention. You’re getting Australian-designed compression gear that uses PWX fabric to apply targeted pressure across your quads, hamstrings, and glutes during explosive movements like sprints, plyometrics, or heavy lifting sessions. The compression fit sits tighter than standard boxer briefs, which means you need to size carefully based on 2XU’s charts rather than your usual underwear size.
Sweat and breathability
2XU’s PWX fabric combines nylon and Lycra in a high-density weave that wicks moisture while maintaining compression across your muscles. The material pulls sweat away from your skin through engineered channels that direct moisture towards the fabric surface for faster evaporation. You’ll notice mesh panels positioned along the inner thighs and behind the knees where airflow matters most during intense training. The compression fit creates less air circulation than looser boxer briefs, so these work best for shorter, high-output sessions rather than extended endurance training where ventilation becomes critical.
2XU’s graduated compression applies targeted pressure to major muscle groups while maintaining effective moisture management through engineered fabric channels.
Support and chafe control
The compression design eliminates excess fabric that causes bunching or ride-up during movement, keeping everything locked in place through the full range of motion. 2XU uses flat-lock seams positioned away from high-friction zones to reduce rubbing where your thighs meet during running or cycling. You get muscular support that reduces vibration and fatigue during jumping or sprinting while the tight fit prevents skin-on-skin contact that leads to chafing. The graduated compression increases blood flow to working muscles, which helps with both performance and recovery between training sessions.
Price and availability in Australia
2XU compression shorts retail between $70 and $90 per pair at Australian stockists including Rebel Sport, The Iconic, and 2XU’s Melbourne flagship store. You’ll find free shipping on orders over $100 from most online retailers, with delivery taking 3 to 5 business days to metro areas. The brand offers size exchange options within 30 days for unworn items.
8. Uniqlo AIRism ultra seamless boxer briefs
Uniqlo AIRism ultra seamless boxer briefs bring Japanese fabric technology to the workout underwear category at a price point that undercuts most options on this list of the best workout underwear for men. The brand engineered AIRism fabric specifically to handle heat and moisture in humid climates, using a micro-mesh construction that creates air pockets between your skin and the outer layer. You’re getting a genuinely seamless design that eliminates the stitched seams responsible for most chafing during athletic activity. Uniqlo positions these as an everyday comfort option that works across casual wear and light to moderate training, making them practical for blokes who want versatile underwear rather than gear built exclusively for high-intensity workouts.
Sweat and breathability
AIRism fabric uses a nylon-polyester blend with integrated moisture management that pulls sweat away from your skin while maintaining a lightweight feel during movement. Uniqlo added micro-denier fibres to the construction that create channels for air circulation even when the fabric sits flush against your body. You get faster drying times compared to cotton because the synthetic blend releases moisture rather than holding it within the fibres. The ultra-seamless design reduces the thick overlapping sections that trap heat against your skin, creating a cooler overall experience during warm-weather training or indoor gym sessions where ventilation matters.
Uniqlo’s AIRism micro-mesh construction creates air pockets that enhance breathability while maintaining effective moisture control during athletic activity.
Support and chafe control
The seamless construction eliminates raised edges and stitching that rub against your skin during repetitive movements like running or cycling. Uniqlo uses a contoured pouch design that provides basic support without the specialized separation you get from dedicated pouch underwear like SLY Collective or Saxx. You get a close fit that prevents bunching while allowing natural movement patterns, though the lack of a dedicated support system means these work better for moderate activity rather than explosive training that requires maximum stability. The flat waistband sits comfortably without digging in or rolling during core exercises.
Price and availability in Australia
You’ll find AIRism ultra seamless boxer briefs at Uniqlo stores across Sydney, Melbourne, and Brisbane for around $19.90 per pair, making them one of the most affordable options on this list. The brand offers multi-pack discounts that bring the per-unit cost down further when you buy three or more pairs together. Delivery from Uniqlo’s Australian website takes 3 to 7 business days to metro areas, with free shipping available on orders over $50.
9. Smartwool merino boxer brief
Smartwool merino boxer briefs bring natural fibre performance to the best workout underwear for men category through wool’s unique moisture management properties and temperature regulation capabilities. The brand uses merino wool sourced from New Zealand rather than synthetic fabrics, which changes how the underwear handles sweat and odour during training sessions. You’re getting a material that naturally resists bacterial growth and regulates temperature across different climates, making these suitable for year-round training in Australia’s varied conditions. Smartwool engineered the fit to sit close to your body without compression, using a slim cut that prevents bunching while allowing full range of motion during exercises that require flexibility.
Sweat and breathability
Merino wool absorbs moisture into its fibres rather than letting it sit on your skin, which means you feel drier even when you’re sweating heavily during cardio or circuit training. The material holds up to 30 per cent of its weight in moisture before feeling damp, giving you longer comfort during extended training sessions. Smartwool’s merino fibres naturally regulate temperature by trapping warm air when you’re cold and releasing heat when your body temperature rises, which works well for outdoor training where conditions change throughout your session. You get natural odour resistance because wool’s structure prevents bacteria from multiplying, so these stay fresher between washes compared to synthetic options.
Merino wool’s natural structure absorbs moisture vapour while maintaining a dry feel against your skin, unlike synthetic fabrics that simply wick surface sweat.
Support and chafe control
Smartwool uses flat-lock seams positioned away from high-friction zones to reduce rubbing during running or cycling movements. The merino fabric itself feels softer against your skin compared to polyester or nylon blends, which reduces irritation during long training sessions. You get a contoured pouch design that provides basic support without the specialized separation found in dedicated pouch underwear, making these better suited for moderate-intensity training rather than explosive movements that require maximum stability. The elastic waistband sits flat against your lower abdomen without creating pressure points during core work.
Price and availability in Australia
You’ll find Smartwool merino boxer briefs at outdoor retailers including Paddy Pallin, Wild Earth, and Kathmandu for around $50 to $60 per pair. Most stockists offer free shipping on orders over $75, with delivery taking 5 to 7 business days to metro areas. The brand’s return policies typically cover 30 days for unworn items with original tags attached.
10. Icebreaker Anatomica merino boxer briefs
Icebreaker Anatomica merino boxer briefs compete directly with Smartwool in the natural fibre performance category, using New Zealand merino wool to handle moisture and temperature regulation during training. The brand engineered these specifically for athletic activity rather than casual wear, incorporating a body-mapped construction that places different fabric weights in zones based on where your body generates the most heat and sweat. You’re getting a contoured fit that follows your anatomy more closely than traditional merino underwear, with strategically positioned seams that reduce bulk and friction during movement. Icebreaker positions these as year-round training underwear that adapts to different climates without requiring multiple seasonal options.
Sweat and breathability
Icebreaker uses 18.9-micron merino wool fibres that create a softer feel against your skin while maintaining the material’s natural moisture-wicking properties. The wool absorbs sweat vapour before it becomes liquid on your skin, which keeps you feeling drier during high-intensity training compared to synthetic fabrics that only manage surface moisture. You get natural temperature regulation because merino fibres trap air pockets that insulate when you’re cold and release heat when your body temperature rises during exercise. The body-mapped construction uses lighter-weight mesh panels across the inner thighs and lower back where ventilation matters most, creating targeted airflow without compromising the underwear’s overall structure.
Icebreaker’s body-mapped merino construction places different fabric weights strategically to optimise both temperature control and moisture management during athletic activity.
Support and chafe control
The Anatomica design uses flat-lock seams positioned away from friction zones where your thighs meet during running or cycling movements. Icebreaker employs a contoured pouch that provides support without the specialized separation found in dedicated pouch underwear like those in the top spots of the best workout underwear for men category. Merino wool naturally resists odour-causing bacteria, so these stay fresher between washes during multi-day training blocks. You get a comfortable fit that prevents bunching while allowing full range of motion during squats, lunges, or flexibility work.
Price and availability in Australia
You’ll find Icebreaker Anatomica merino boxer briefs at outdoor retailers including Paddy Pallin, Kathmandu, and Icebreaker stores for around $55 to $65 per pair. Most stockists offer free shipping on orders over $100, with delivery taking 5 to 7 business days to metro areas.
11. Runderwear recycled running boxers
Runderwear recycled running boxers earn a spot on the best workout underwear for men list through the brand’s singular focus on eliminating chafing for runners while using recycled materials in their construction. The UK-based brand built its reputation specifically around addressing the friction issues that plague distance runners, cyclists, and triathletes during long training sessions. You’re getting underwear engineered with seamless construction and a design that removes every potential pressure point where fabric meets skin during repetitive motion. Runderwear uses recycled polyamide in their fabric blend, which gives these an environmental angle without compromising the performance characteristics you need during intense cardio work or endurance training.
Sweat and breathability
The recycled polyamide blend pulls moisture away from your skin using engineered wicking channels that spread sweat across the fabric surface for faster evaporation during sustained effort. Runderwear incorporates mesh panels along the waistband and inner thighs to increase airflow where your body generates the most heat during running or cycling. You get quick-drying performance that matches synthetic options from bigger brands, making these practical for situations where you need to pack sweaty gear immediately after training. The fabric maintains its shape and wicking properties even after repeated washes, which matters when you’re cycling through training gear multiple times per week.
Support and chafe control
Runderwear eliminates traditional seams entirely through their seamless construction technology, removing the raised edges that cause rubbing during long runs or bike rides. The brand uses a contoured pouch design that provides basic support while preventing bunching during movement, though you won’t get the specialized separation found in dedicated pouch underwear from brands like SLY Collective. You get a close fit that keeps everything stable during road running, trail work, or indoor cardio without excess fabric shifting around. The waistband sits flat against your lower abdomen without creating pressure points during core work or when wearing a running belt.

12. Patagonia Sender boxer briefs
Patagonia Sender boxer briefs round out the best workout underwear for men list by bringing the brand’s environmental commitment and outdoor performance expertise to training underwear. The company built these using recycled nylon and spandex in a construction that prioritises comfort during dynamic movement while maintaining Patagonia’s standards for sustainability. You’re getting a 5.5-inch inseam that provides adequate coverage without excess fabric bunching during squats or running strides. Patagonia engineered these specifically for active use rather than casual wear, incorporating features that matter during training sessions while using materials that align with the brand’s Fair Trade certification and environmental values.
Sweat and breathability
The recycled nylon blend wicks moisture away from your skin using engineered channels that spread sweat across the fabric surface for quicker evaporation during cardio or strength training. Patagonia incorporated mesh panels along the inner thighs where airflow matters most when your body temperature rises during intense activity.

Final take
Finding the best workout underwear for men comes down to three priorities: preventing chafing, managing sweat effectively, and staying in place during movement. You’ve seen how different brands approach these challenges through pouch designs, seamless construction, compression fits, and fabric technology. The options on this list range from budget-friendly synthetic blends to premium merino wool, each with strengths that match specific training styles and preferences.
SLY Collective’s bamboo boxer briefs top this comparison because the built-in ball pouch eliminates the root cause of chafing rather than just managing symptoms. You get Australian-designed underwear that combines superior support with natural temperature regulation and a comfort guarantee that backs up the performance claims. If you’re tired of adjusting your underwear mid-workout or dealing with raw thighs after training, grab a 3-pack of SLY Collective bamboo boxer briefs and experience the difference pouch technology makes during your next session.
