8 Best Men’s Athletic Underwear for Workouts in Australia

That burning sensation between your thighs after a long run. Sweat pooling in places that make you uncomfortable. The constant need to adjust yourself during squats because your underwear has bunched up again. If you’ve experienced any of these, you already know that regular cotton underwear wasn’t designed for athletic performance. You need gear that actually works when you’re pushing your body hard. Underwear that breathes when you sweat, supports without restricting, and stays in place no matter how you move.

This guide breaks down eight of the best men’s athletic underwear options you can buy in Australia right now. We’ve examined performance fabrics, support systems, moisture management, and practical use cases for different training styles. From bamboo boxer briefs with built in pouches to compression shorts designed for runners, you’ll find options that match how you train. Whether you’re grinding through heavy deadlifts, pounding the pavement for kilometres, or pushing through high intensity circuits, these picks will keep you comfortable and focused on your workout instead of your underwear.

1. SLY Collective bamboo pouch boxer briefs

SLY Collective tops this list because these boxer briefs solve the core problem that plagues most men during workouts: chafing and discomfort. You get bamboo fabric that breathes naturally, a built in pouch that separates your anatomy, and a longer leg design that prevents ride up during movement. These aren’t just comfortable for casual wear. They perform when you’re pushing hard in the gym or pounding kilometres on the road.

Performance and fabric

Support and comfort

That built in inner pouch changes everything. It separates skin from skin contact, which eliminates the friction that causes chafing during repetitive movements like running or cycling. You get structured support that keeps everything in place without compression that restricts blood flow. The longer leg design extends past your thigh, preventing the bunching and riding up that ruins your focus mid set.

“The ergonomic shape holds the testes in a natural, slightly elevated position, lifting and separating, while promoting better blood flow.”

2. Under Armour Tech boxerjock

Under Armour built its reputation on performance gear, and the Tech boxerjock delivers that same athletic focus to your underwear drawer. You get moisture-wicking technology that’s been refined through years of feedback from athletes who train hard. The 4-way stretch construction moves with your body instead of restricting it, which makes these a solid choice when you need men’s athletic underwear that won’t hold you back during intense sessions.

Performance and fabric

The Tech boxerjock uses Under Armour’s signature HeatGear fabric, a polyester-elastane blend designed to pull sweat away from your skin and dry quickly. You’ll notice the ultra-soft material feels smooth against your body without that sticky synthetic sensation cheaper athletic underwear creates. The fabric’s lightweight construction means you barely feel it during workouts, and the anti-odour technology prevents that post-workout stench from building up in your gym bag.

Support and comfort

Under Armour designed these with a working fly and an updated pouch that provides support without excessive compression. The anti-chafe seams sit flat against your skin to reduce friction during repetitive movements. You get a flexible waistband that stays put without digging into your waist when you bend or twist. The 6-inch inseam prevents ride-up during squats and lunges while still fitting comfortably under your training shorts.

“The 4-way stretch construction moves with your body instead of restricting it.”

Best use cases for workouts

These boxerjocks perform best during strength training sessions where you’re moving through multiple planes of motion. CrossFit athletes appreciate how they handle everything from box jumps to Olympic lifts. The moisture management system also makes them suitable for moderate cardio sessions, though runners logging serious kilometres might want something with more specialised anti-chafe features.

Price and where to buy

You can find Under Armour Tech boxerjocks at major Australian retailers including Rebel Sport and the official Under Armour Australia website. Prices typically range from $30 to $40 per pair, with multi-packs offering better value when you’re stocking up your drawer.

3. Nike Dri-FIT ADV boxer briefs

Nike’s Dri-FIT ADV boxer briefs represent the brand’s most advanced athletic underwear technology. You get engineered mesh zones placed exactly where your body generates the most heat during training, combined with Nike’s proven moisture management system that’s been refined through decades of athletic gear development. These boxer briefs target serious athletes who need maximum breathability without sacrificing support during high output sessions.

Performance and fabric

The ADV (Advanced) designation means you’re getting Nike’s premium fabric blend that combines polyester with strategic mesh panels for targeted ventilation. Your body stays cooler because the mesh zones sit at your inner thighs and lower back where heat builds up fastest during intense exercise. The Dri-FIT technology pulls sweat away from your skin and spreads it across the fabric surface for rapid evaporation. This system works better than basic moisture-wicking materials because it actively moves perspiration instead of just absorbing it.

Support and comfort

Nike engineered these with a contoured pouch that provides anatomical support without the bulky feel of compression shorts. The seamless construction at high friction points reduces chafing during running and explosive movements. You’ll notice the flat-lock seams only where they’re structurally necessary, which means less irritation against your skin. The stretchy waistband includes a bonded Nike logo that won’t dig into your waist when you’re bent over doing deadlifts or sit-ups.

“The mesh zones sit at your inner thighs and lower back where heat builds up fastest during intense exercise.”

Best use cases for workouts

These boxer briefs excel during cardio-intensive training where ventilation matters most. Distance runners benefit from the targeted mesh panels that prevent overheating during long kilometres. HIIT athletes appreciate how the fabric handles repeated sweat cycles without becoming saturated or heavy.

Price and where to buy

You can purchase Nike Dri-FIT ADV boxer briefs through the official Nike Australia website and major sporting retailers across Australia. Expect to pay between $35 and $50 per pair depending on sales and colour options.

4. Step One men’s bamboo trunks

Step One brings Australian-designed bamboo viscose trunks that compete directly with the best men’s athletic underwear available locally. You get the natural benefits of bamboo viscose paired with anti-chafe technology that’s been tested by over 65,000 customers. These trunks use a shorter leg length compared to boxer briefs, which makes them ideal when you want freedom of movement without excess fabric bunching under your training shorts.

Performance and fabric

The bamboo viscose construction delivers superior moisture management compared to traditional cotton or basic synthetic blends. Your skin stays drier because the fabric absorbs moisture and releases it quickly into the air. Step One’s material also provides natural temperature regulation that keeps you cooler during intense sessions and warmer during outdoor winter training. The fabric resists odour buildup naturally, which means you can push through multiple training sessions before these trunks need washing.

Support and comfort

Step One designed these trunks with anti-chafe technology that reduces friction at contact points during repetitive movements. The shorter trunk style gives you support without the longer leg of boxer briefs, which some athletes prefer for maximum mobility. You get a sweat-wicking waistband that stays comfortable even when soaked, and flatlock seams that sit smooth against your skin during squats, lunges, and running strides.

“The bamboo viscose construction delivers superior moisture management compared to traditional cotton or basic synthetic blends.”

Best use cases for workouts

These trunks perform exceptionally well during warm weather training when you need maximum ventilation. Athletes who train in hot gyms or outdoor conditions benefit from the shorter leg design that exposes more skin for cooling. They work brilliantly for yoga and flexibility training where longer legs might restrict your range of motion during deep stretches.

Price and where to buy

You can purchase Step One bamboo trunks directly from stepone.life with delivery across Australia. Prices start around $30 per pair, with bundle deals available when you buy multiple pairs.

5. Debriefs MicroModal boxer briefs

Debriefs built these boxer briefs around MicroModal fabric, which sits at the premium end of men’s athletic underwear materials. You get Australian-designed underwear that combines softness with serious performance capabilities, particularly for athletes who train in varied conditions. The brand focuses on using sustainable materials without compromising the technical features you need during intense workouts.

Performance and fabric

MicroModal delivers three times the moisture absorption of regular cotton while drying significantly faster than traditional fabrics. Your skin stays drier because the ultra-fine fibres pull sweat away efficiently and spread it across a larger surface area for rapid evaporation. The fabric maintains its breathable structure even when wet, which prevents that clammy feeling during extended training sessions. You’ll notice the material stays soft wash after wash, unlike synthetic blends that develop a rough texture over time.

Support and comfort

These boxer briefs feature seamless construction at critical friction points to prevent chafing during running and explosive movements. The ergonomic pouch provides anatomical support without compression that restricts blood flow. You get a lay-flat waistband that won’t roll or dig into your waist when you’re bent over doing rows or planks. The fabric’s natural stretch moves with your body through full range of motion exercises.

“MicroModal delivers three times the moisture absorption of regular cotton while drying significantly faster.”

Best use cases for workouts

These boxer briefs excel during strength training sessions where you move through multiple exercises with varying intensities. Gym-goers appreciate how the fabric handles temperature changes between warm-up cardio and heavy lifting. The moisture management also makes them suitable for moderate running sessions up to 10 kilometres.

Price and where to buy

You can purchase Debriefs MicroModal boxer briefs from debriefs.com.au with delivery throughout Australia. Prices typically range around $30 per pair, with multipack options available for better value.

6. SAXX Kinetic light compression boxers

SAXX Kinetic light compression boxers bring targeted compression technology to men’s athletic underwear without the restrictive feel of full compression shorts. You get micro-mesh construction that delivers support to your quads and hamstrings while maintaining breathability during intense training sessions. The compression element works differently from traditional tight-fitting underwear because it focuses on key muscle groups rather than squeezing everything uniformly.

Performance and fabric

The micro-mesh fabric creates a lightweight barrier that wicks moisture away from your skin while allowing air to circulate freely. Your body stays cooler because sweat evaporates quickly through the mesh structure instead of pooling against your skin. SAXX engineered this material with odour-resistant properties that prevent bacterial buildup during extended wear, which means you won’t smell like a locker room after pushing through multiple training sessions. The fabric maintains its compression qualities even when wet, unlike cheaper alternatives that lose their shape when saturated with sweat.

Support and comfort

SAXX’s signature BallPark Pouch separates your anatomy to prevent friction and chafing during repetitive movements. The compression panels target your thighs without constricting your waist or groin area, which gives you support where it matters most. You’ll notice the flat-lock seams sit smooth against your skin instead of creating pressure points during squats or lunges. The waistband stays secure without rolling or digging into your core when you’re bent over during exercises.

“The compression panels target your thighs without constricting your waist or groin area.”

Best use cases for workouts

These boxers excel during running sessions where you need muscle support without excessive fabric. Endurance athletes benefit from the compression that helps reduce muscle fatigue during long training runs. The design also works brilliantly for leg-focused training days when you’re hammering through squats, lunges, and deadlifts.

Price and where to buy

You can purchase SAXX Kinetic light compression boxers from major Australian sporting retailers and online stores. Prices typically sit around $38 to $45 per pair depending on current promotions and colour options.

7. Lululemon Always In Motion boxers

Lululemon brings athletic expertise from their yoga and training apparel into men’s athletic underwear with the Always In Motion boxers. You get 7-inch inseam coverage that prevents ride-up during deep squats and lunges, combined with four-way stretch that moves through every plane of motion. These boxers target athletes who prioritise flexibility and comfort during training sessions that demand unrestricted movement.

Performance and fabric

The viscose-modal blend (95% viscose, 5% elastane) creates a soft, stretchy material that wicks moisture efficiently while maintaining breathability. Your body stays comfortable because the fabric pulls sweat away from your skin and dries quickly between exercise sets. Lululemon engineered this material with anti-odour technology that prevents bacterial buildup during extended wear, which means you can transition from gym to post-workout errands without smelling like sweat.

Support and comfort

These boxers feature a contour pouch that provides anatomical support without compression that restricts blood flow or movement. The four-way stretch construction flexes with your body during yoga flows, weightlifting sessions, and cardio intervals. You’ll notice the flat waistband sits comfortably against your skin without rolling when you bend or twist through exercises.

“The four-way stretch construction flexes with your body during yoga flows, weightlifting sessions, and cardio intervals.”

Best use cases for workouts

These boxers excel during flexibility-focused training like yoga, pilates, and mobility work where you need maximum range of motion. Athletes who train in multiple disciplines appreciate how they handle everything from stretching to strength work. The longer inseam also makes them suitable for running sessions where you want coverage without excess fabric.

Price and where to buy

You can purchase Lululemon Always In Motion boxers from Lululemon Australia stores and their website. Prices typically sit around $25 to $32 per pair, with three-pack options offering better value when you’re building your training underwear collection.

8. Uniqlo AIRism boxer briefs

Uniqlo delivers budget-friendly men’s athletic underwear that performs surprisingly well for its price point. The AIRism boxer briefs use advanced Japanese fabric technology designed to keep your body cool and dry during workouts without the premium price tag attached to specialist sports brands. You get reliable moisture management and comfort that makes these an excellent choice when you’re building a training underwear collection on a reasonable budget.

Performance and fabric

The AIRism fabric combines nylon and spandex with microscopic air pockets woven into the material structure. Your body stays cooler because these air pockets create ventilation channels that allow heat to escape while pulling moisture away from your skin. Uniqlo engineered this material to feel smooth and cool to the touch, which provides immediate comfort when you pull them on before training. The fabric also includes odour control technology that prevents bacterial buildup during sweaty sessions.

Support and comfort

These boxer briefs feature a working fly and standard pouch design that provides adequate support for most training activities. The flat seams reduce friction at contact points, though they’re not as advanced as the seamless construction found in premium options. You get a flexible waistband that stays secure without excessive compression, and the 6-inch inseam prevents ride-up during squats and lunges.

“The AIRism fabric combines nylon and spandex with microscopic air pockets woven into the material structure.”

Best use cases for workouts

These boxer briefs work best during moderate-intensity training sessions like circuit training, casual runs, and general gym workouts. Budget-conscious athletes appreciate how they handle everyday training without breaking down quickly.

Price and where to buy

You can purchase Uniqlo AIRism boxer briefs from Uniqlo Australia stores and their website. Prices sit around $15 to $20 per pair, making them one of the most affordable quality options available.

Final thoughts

You’ve now seen eight solid options for men’s athletic underwear that deliver performance where it matters most. Your choice ultimately depends on what type of training you do and which features matter most to your comfort. Runners might prioritise anti-chafe technology and moisture management, while strength athletes often need unrestricted range of motion and durability through heavy compound movements.

Budget plays a role, but remember that quality athletic underwear lasts longer and performs better than cheap alternatives that break down after a few washes. Spending an extra $10 to $20 per pair often saves you money in the long run when you’re not replacing worn-out underwear every few months. Performance fabrics like bamboo, MicroModal, and advanced synthetics justify their cost through superior comfort and longevity.

Your training deserves gear that supports your effort instead of creating distractions. If you’re ready to upgrade to underwear that actually works during intense sessions, check out SLY Collective’s bamboo pouch boxer briefs for Australian-designed comfort with proven anti-chafe technology.
