Nothing ruins a solid gym session faster than underwear that rides up, bunches, or leaves you with chafing that burns for days. If you’ve ever cut a workout short because your boxers turned against you, you already know that finding the best type of underwear for gym workouts matters more than most blokes realise. The right pair can mean the difference between smashing your personal best and hobbling to the car park.
Your underwear does serious work during exercise. It needs to manage sweat, prevent friction, support your anatomy, and stay put through squats, sprints, and everything in between. Yet most men grab whatever’s in the drawer without a second thought. That’s a mistake. Performance underwear isn’t just marketing fluff, it’s engineered to handle the specific demands of physical activity, from moisture-wicking fabrics to strategic support features that keep everything where it should be.
At SLY Collective, we’ve spent years perfecting men’s underwear with built-in pouch support and breathable bamboo fabric designed to eliminate chafing and regulate temperature. That expertise has given us a clear view of what actually works when you’re pushing your body hard. In this guide, we’ve rounded up 12 top picks across different styles and price points, breaking down what makes each one suited for the gym, so you can train without distraction and focus on what actually matters: your workout.
1. Pouch boxer briefs (SLY Collective bamboo)
Pouch boxer briefs solve the biggest problem most gym-goers face: friction between your thighs and uncomfortable skin-on-skin contact. SLY Collective’s bamboo version takes this design further with a built-in anatomical pouch that separates and supports your anatomy while you move, combined with bamboo fabric that naturally regulates temperature and wicks moisture. When you’re choosing the best type of underwear for gym workouts, pouch boxer briefs consistently rank at the top because they address multiple pain points in one design. The longer leg length prevents ride-up during deep squats or lunges, while the pouch construction eliminates the constant need to adjust yourself between sets.
Why it works in the gym
Your body generates serious heat during exercise, and traditional flat-front underwear traps moisture against your skin, creating the perfect environment for chafing and irritation. The anatomical pouch in SLY Collective boxer briefs lifts and separates everything, allowing air to circulate freely and preventing the skin-on-skin friction that causes painful raw spots. Bamboo fabric naturally absorbs 40% more moisture than cotton while drying faster, which means sweat doesn’t pool in uncomfortable places during high-intensity training.
The pouch design keeps everything stable during dynamic movements like burpees, box jumps, and sprint intervals, giving you genuine support without compression that restricts blood flow.
During compound lifts and explosive movements, you need underwear that stays put without strangling you. The structured pouch provides targeted support without excessive compression, and the longer legs prevent the fabric from bunching or rolling up your thighs when you drop into a squat or spread your legs for deadlifts. Bamboo’s natural antibacterial properties also keep odour under control, even during back-to-back training sessions.
Best for
Blokes who suffer from regular chafing will immediately notice the difference with pouch boxer briefs. If you’ve tried everything from powder to compression shorts and still end up with angry red marks after leg day, the pouch construction eliminates the root cause by preventing direct skin contact. Heavy lifters and CrossFit athletes particularly benefit from the stable support during dynamic movements that doesn’t shift or bunch when you’re moving through a full range of motion.
Anyone training in hot conditions or prone to overheating will appreciate bamboo’s temperature-regulating properties. The fabric breathes better than synthetic blends while managing moisture more effectively than cotton, making these ideal for summer training or heated studio classes.
Watch-outs
Pouch underwear requires a different sizing approach than traditional boxer briefs. You need the pouch to fit your anatomy properly, so if you’re between sizes, going up usually works better than squeezing into a smaller pair. The structure won’t provide the intended benefits if the fabric is stretched too tight.
Bamboo fabric needs slightly different care than synthetic performance gear. Avoid high heat in the dryer, as it can damage the fibres and reduce the fabric’s moisture-wicking properties over time. Air drying extends the life of the underwear significantly.
Typical price in Australia
Quality pouch boxer briefs in bamboo fabric typically range from $35 to $45 per pair in Australia. SLY Collective offers multi-pack options that bring the per-pair cost down, and the durability of bamboo fabric means these last considerably longer than cheap synthetic alternatives, making them a better investment over time. Budget around $100 for a three-pack to build a solid rotation for your weekly training schedule.
2. Long-leg boxer briefs
Long-leg boxer briefs extend further down your thighs than standard cuts, typically offering a 7-9 inch inseam compared to the usual 5-6 inches. This extra coverage creates a barrier between your skin and prevents the thigh-on-thigh chafing that plagues blokes during leg-intensive workouts. When you’re evaluating the best type of underwear for gym workouts, longer legs consistently rank high for runners, cyclists, and anyone doing movements that involve repetitive leg motion. The extended fabric stays locked in place and doesn’t ride up when you’re pushing through high-rep squats or pounding out kilometres on the treadmill.
Why it works in the gym
The longer inseam serves a specific purpose: it prevents friction where your thighs rub together during movement. Every stride, squat, or lunge creates contact between your inner thighs, and without proper coverage, that repeated friction breaks down your skin rapidly. Extended legs keep fabric between those contact points, eliminating the painful raw spots that develop during endurance training or high-volume leg sessions.
Longer coverage means the underwear stays anchored during dynamic movements instead of bunching around your groin or rolling up your legs.
These boxer briefs work particularly well under fitted training shorts or tights because they create smooth lines without visible bunching. The extra length also prevents your shorts from riding up separately from your underwear, keeping everything aligned as you move.
Best for
Distance runners and cyclists benefit most from long-leg boxer briefs because the extended coverage protects against chafing during repetitive motion. If you’re regularly logging 10k runs or spending hours in the saddle, this style prevents the gradual friction damage that builds over long training sessions.
Blokes with larger thighs or those who carry more mass in their legs will find the extra coverage prevents skin contact that shorter styles can’t address.
Watch-outs
The longer legs can feel restrictive if you’re not used to them, particularly during wide-stance movements like sumo squats or lateral lunges. You’ll need to ensure the fabric has enough stretch to accommodate full range of motion without pulling tight across your thighs.
Typical price in Australia
Quality long-leg boxer briefs typically cost $25 to $40 per pair in Australia. Performance brands with moisture-wicking fabrics sit at the higher end, while basic cotton versions start around $20. Budget $80 to $120 for a three-pack from established activewear brands.
3. Seamless boxer briefs
Seamless boxer briefs eliminate the stitched seams that typically run along the sides, crotch, and waistband of traditional underwear. Instead, manufacturers use circular knitting technology to create a single continuous piece of fabric that moulds to your body without any raised edges or rigid seam lines. This construction method dramatically reduces friction points against your skin and creates a smooth silhouette under fitted gym clothes. When you’re comparing the best type of underwear for gym workouts, seamless styles stand out for blokes who train in tight shorts or leggings and want zero visible lines or chafing from seam placement.
Why it works in the gym
Traditional seams create raised ridges that dig into your skin during repetitive movements, particularly where elastic waistbands meet fabric or where leg openings curve around your thighs. Seamless construction removes these pressure points entirely, distributing fabric tension evenly across the garment. You won’t develop the red marks and irritation that appear after hours of training when seams rub against the same spots repeatedly.
The continuous fabric construction prevents the seam separation and breakdown that occurs in traditional underwear after repeated washing and stretching.
Seamless boxer briefs also create a second-skin feel that moves with your body instead of against it. The stretchy, knitted fabric expands and contracts during squats, lunges, and dynamic movements without creating bunching or pulling sensations.
Best for
Blokes who wear compression tights or fitted training shorts benefit most from seamless construction because the underwear creates no visible panty lines or bulges. If you do yoga, Pilates, or studio classes where you’re surrounded by mirrors, seamless styles maintain a clean appearance.
Anyone with sensitive skin or existing chafing problems will notice immediate relief from eliminating seam friction.
Watch-outs
Seamless doesn’t automatically mean moisture-wicking or breathable. You still need to check the fabric composition, as some seamless styles use synthetic blends that trap heat despite the construction method.
Typical price in Australia
Seamless boxer briefs typically range from $30 to $50 per pair in Australia. Performance brands with advanced fabrics sit at the higher end, while basic seamless styles start around $25. Budget $90 to $130 for a three-pack from quality activewear brands.
4. Compression boxer briefs
Compression boxer briefs apply graduated pressure across your thighs and groin to support muscles during intense training. This style uses stretchy, tight-fitting fabrics that hug your body firmly without cutting off circulation, creating a supportive layer that reduces muscle vibration during high-impact movements. When you’re researching the best type of underwear for gym workouts, compression styles emerge as a favourite among athletes who need maximum support during explosive exercises and heavy lifting. The snug fit eliminates excess fabric that could bunch or shift, keeping everything locked in place from your first rep to your last.
Why it works in the gym
Compression fabric reduces muscle oscillation during jumping, running, and dynamic movements, which helps decrease fatigue and soreness. Your muscles work more efficiently when they’re supported, and the constant pressure improves blood flow by encouraging circulation back toward your heart. This enhanced circulation helps clear metabolic waste products faster during recovery between sets.
The tight fit prevents your underwear from riding up or shifting position, eliminating mid-workout adjustments that break your focus.
Athletes performing Olympic lifts, plyometrics, or CrossFit movements benefit from the stabilising effect on their core and upper legs. The compression also reduces chafing by keeping fabric firmly against your skin instead of allowing it to slide and create friction.
Best for
Powerlifters and weightlifters gain the most from compression boxer briefs because the firm support aids stability during heavy compound movements. If you’re squatting or deadlifting serious weight, the compression provides an extra layer of proprioceptive feedback that helps you maintain proper form.
Sprint athletes and HIIT enthusiasts will appreciate how compression manages muscle fatigue during explosive efforts.
Watch-outs
Compression underwear needs to fit precisely. Too tight restricts blood flow and creates discomfort, while too loose fails to provide proper compression benefits. You’ll need to follow sizing charts carefully rather than guessing.
Typical price in Australia
Quality compression boxer briefs range from $35 to $60 per pair in Australia. Medical-grade compression sits at the higher end, while athletic compression starts around $30. Budget $100 to $150 for a three-pack from performance brands.
5. Briefs
Briefs offer minimal coverage with high-cut leg openings that end well above your thighs, providing unrestricted movement during gym sessions. This classic style eliminates the fabric that extends down your legs in boxer briefs, which means zero material to bunch or ride up when you’re moving through deep ranges of motion. While briefs aren’t the most popular choice when blokes discuss the best type of underwear for gym workouts, they deliver specific advantages for certain training styles and body types. The compact design keeps everything supported without excess fabric getting in the way during explosive movements or flexibility work.
Why it works in the gym
Briefs give you complete freedom at the hip joint and upper thighs because nothing wraps around your legs. During movements that require maximum mobility like high kicks, split squats, or wide-stance exercises, you won’t feel any fabric pulling or restricting your range. The snug fit around your waist and groin provides reliable support without the compression of longer styles, and quality briefs use elastic leg openings that stay put without digging into your skin.
The minimal design means less fabric to manage moisture, but you need performance materials that can handle sweat effectively in the small coverage area.
Best for
Gymnasts, martial artists, and yoga practitioners benefit most from briefs because the unrestricted leg movement supports the extreme flexibility their training demands. If your workout involves splits, high kicks, or complex bodyweight positions, briefs won’t interfere with your mobility.
Blokes who overheat easily during training will appreciate the reduced fabric coverage that allows maximum airflow.
Watch-outs
Briefs offer no protection against thigh chafing, so they’re unsuitable if friction between your legs is a problem. You’ll need smooth inner thighs or accept that skin-on-skin contact will occur during most exercises.
Typical price in Australia
Performance briefs typically cost $20 to $35 per pair in Australia. Athletic brands with moisture-wicking fabrics sit around $25-30, while basic cotton versions start at $15. Budget $60 to $90 for a three-pack from quality sportswear brands.
6. Trunks
Trunks sit between briefs and boxer briefs in the coverage spectrum, offering a square-cut leg opening that typically ends 3-4 inches down your thigh. This style provides more coverage than traditional briefs while avoiding the longer leg length of boxer briefs, creating a compact fit that supports without excess fabric. When blokes compare the best type of underwear for gym workouts, trunks often get overlooked despite delivering a balanced combination of support, mobility, and minimal bulk. The shorter leg design prevents bunching during leg exercises while still covering enough surface area to reduce friction between your thighs and the inside of your shorts.
Why it works in the gym
Trunks eliminate the ride-up problem that plagues standard boxer briefs during certain movements. The shorter legs don’t have enough length to bunch or roll up your thighs, so they stay anchored in position throughout your workout. You get adequate coverage to prevent most chafing issues without dealing with fabric that extends too far down your legs and restricts movement during deep squats or wide-stance exercises.
The square-cut design creates clean lines under fitted gym shorts and prevents the visible bunching that occurs with longer styles.
Best for
Bodybuilders and physique athletes benefit from trunks because the shorter cut doesn’t interfere with posing or flexibility assessments. If your training involves frequent checks of muscle definition or form in mirrors, trunks provide coverage without visible lines under compression shorts.
Blokes who find boxer briefs too long but briefs too minimal will appreciate trunks as the middle-ground option that balances coverage with mobility.
Watch-outs
Trunks offer limited protection against inner-thigh chafing compared to longer styles. If friction between your legs is a recurring problem during cardio or leg training, the shorter coverage won’t provide enough barrier protection.
Typical price in Australia
Quality trunks range from $25 to $40 per pair in Australia. Performance brands with moisture-wicking fabrics cost $30-35, while basic cotton versions start around $20. Budget $70 to $100 for a three-pack from established sportswear brands.
7. Jockstrap
Jockstraps provide targeted frontal support with minimal rear coverage, using an elastic waistband and two leg straps that frame your backside while a pouch holds everything in place at the front. Originally designed for cyclists in 1874, this style eliminates fabric between your glutes entirely, which maximises airflow and prevents sweat accumulation in areas where traditional underwear traps moisture. While jockstraps aren’t mainstream when blokes consider the best type of underwear for gym workouts, they deliver unmatched ventilation and support for specific training scenarios. The exposed design won’t suit everyone’s comfort level, but athletes who prioritise cooling and stability during intense sessions often swear by them.
Why it works in the gym
The open-back design creates unrestricted airflow across your entire rear, which keeps you significantly cooler during high-intensity training compared to full-coverage underwear. Your body generates tremendous heat during heavy lifting or cardio, and eliminating fabric from your glutes allows that heat to dissipate instead of getting trapped against your skin. The frontal pouch provides firm support that prevents movement and discomfort during jumping, running, or explosive exercises.
Jockstraps keep everything locked in position without compression, reducing bounce and protecting against impact during contact sports or high-impact movements.
Best for
Rugby players, CrossFit athletes, and martial artists benefit most from jockstraps because the secure frontal support protects during physical contact while the open design prevents overheating. If your training involves frequent impacts, rapid direction changes, or partner work, a jockstrap delivers reliable protection.
Blokes who overheat easily will appreciate the maximum ventilation this style provides.
Watch-outs
Jockstraps offer zero coverage at the back, which means they won’t work under light-coloured or thin gym shorts. You’ll need darker, thicker training gear to maintain modesty.
Typical price in Australia
Athletic jockstraps range from $25 to $45 per pair in Australia. Performance brands with moisture-wicking pouches cost $35-40, while basic cotton versions start around $20. Budget $70 to $110 for a three-pack from sports equipment brands.
8. Mesh-panel performance underwear
Mesh-panel underwear strategically places breathable mesh fabric in high-heat zones like your crotch, inner thighs, and lower back, while using solid fabric for coverage and support in other areas. This hybrid construction targets the sweat accumulation points that cause the most discomfort during training, creating ventilation where you need it most without sacrificing the structure that keeps everything in place. While you’re evaluating the best type of underwear for gym workouts, mesh-panel designs stand out for blokes who train in hot environments or generate excessive sweat during intense sessions. The perforated panels allow air to flow directly against your skin, dramatically improving cooling compared to solid fabrics that trap heat.
Why it works in the gym
Your groin and inner thighs generate more heat than any other covered area during exercise, and traditional underwear traps that warmth against your skin. Mesh panels create direct ventilation channels that pull hot air away from your body while allowing cooler air to reach your skin. This constant airflow prevents the moisture buildup that leads to chafing, bacterial growth, and the uncomfortable swampy feeling that develops during long training sessions.
Strategic mesh placement accelerates sweat evaporation without exposing you or compromising the support your anatomy needs during movement.
Best for
Blokes who train in hot climates or heated facilities benefit most from mesh-panel underwear because the enhanced airflow prevents overheating. If you regularly sweat through standard performance underwear or struggle with heat during summer training, the ventilation makes a noticeable difference.
Athletes doing high-intensity interval training or cardio-heavy sessions will appreciate how mesh panels manage the excessive sweat these workouts generate.
Watch-outs
Mesh panels wear out faster than solid fabric through repeated washing and friction, so you’ll need to replace these sooner than standard underwear.
Typical price in Australia
Mesh-panel performance underwear ranges from $30 to $50 per pair in Australia. Technical athletic brands cost $40-45, while basic mesh versions start around $25. Budget $85 to $130 for a three-pack from established performance brands.
9. Merino wool boxer briefs
Merino wool boxer briefs use natural fibres from merino sheep that deliver temperature regulation and odour control without the synthetic feel of polyester blends. This fabric naturally wicks moisture while maintaining warmth when you need it and cooling you down during intense efforts, creating a self-regulating environment that adapts to your activity level. When you’re assessing the best type of underwear for gym workouts, merino wool represents a premium natural option that performs exceptionally well across varied training conditions. The fine fibres feel soft against your skin instead of scratchy like traditional wool, and the material’s antimicrobial properties keep you fresh through multiple sessions between washes.
Why it works in the gym
Merino wool manages moisture differently than cotton or synthetics by absorbing up to 30% of its weight in water while still feeling dry against your skin. During heavy lifting or cardio, sweat moves into the fibres instead of pooling on your skin’s surface, which prevents that clammy feeling and reduces chafing. The natural crimp in merino fibres creates air pockets that trap body heat when you’re warming up, then release it as your core temperature rises during training.
Merino’s antimicrobial properties prevent bacterial growth that causes odour, letting you wear the same pair through back-to-back sessions without developing that gym-bag smell.
Best for
Blokes who train in cold weather or air-conditioned gyms benefit most from merino’s temperature regulation. The fabric keeps you warm during rest periods between sets without overheating during working sets.
Athletes doing multi-day training camps or travel workouts will appreciate how merino stays fresh longer than synthetic fabrics.
Watch-outs
Merino wool requires gentle washing and air drying to maintain the fibres’ performance properties. High heat damages the natural structure and reduces moisture-wicking effectiveness.
Typical price in Australia
Premium merino wool boxer briefs range from $45 to $70 per pair in Australia. Quality brands cost $50-60, while budget merino starts around $40. Expect to pay $130 to $180 for a three-pack from performance outdoor brands.
10. Synthetic quick-dry boxer briefs
Synthetic quick-dry boxer briefs use polyester, nylon, or spandex blends engineered specifically to pull moisture away from your skin and evaporate it rapidly. These fabrics form the backbone of most technical activewear because they dry significantly faster than natural materials like cotton or bamboo, typically becoming dry to the touch within 30-60 minutes of heavy sweating. When you’re searching for the best type of underwear for gym workouts on a tight budget, synthetic quick-dry styles deliver solid performance without premium pricing. The stretchy, smooth fabric creates a close fit that reduces friction while the moisture-management properties keep you feeling dry even during intense training sessions.
Why it works in the gym
Synthetic fibres have a non-absorbent structure that repels water instead of soaking it up like natural materials. When you sweat during training, moisture moves through tiny channels in the fabric’s weave and spreads across the outer surface where it evaporates quickly. This process keeps the fabric light and prevents that heavy, waterlogged feeling that develops in cotton underwear during cardio or high-rep training.
The rapid-dry capability means your underwear recovers faster between exercises, staying comfortable throughout circuit training or back-to-back workout sessions.
You’ll notice the lightweight feel of synthetic fabrics compared to heavier natural options. This reduced bulk creates less restriction during movement and prevents the sagging that occurs when moisture weighs down your underwear.
Best for
Blokes who train multiple times per day will appreciate how synthetic underwear dries completely between morning and evening sessions. If you’re an athlete, coach, or serious gym-goer who needs fresh gear for consecutive workouts, the quick-dry properties eliminate the need for extensive rotation.
Budget-conscious trainers benefit from synthetics because they cost less than premium natural fabrics while still delivering professional-grade moisture management.
Watch-outs
Synthetic materials can trap odour more readily than natural fibres because bacteria thrive on the fabric’s surface. You’ll need to wash these after every workout to prevent smell buildup.
Typical price in Australia
Synthetic quick-dry boxer briefs range from $15 to $35 per pair in Australia. Basic polyester blends start around $12, while technical athletic versions cost $25-30. Budget $40 to $80 for a three-pack from mainstream sportswear brands.
11. Cotton boxer briefs
Cotton boxer briefs represent the traditional choice that most blokes default to because they feel soft, breathable, and comfortable during everyday wear. This natural fabric offers immediate comfort against your skin without the synthetic feel of polyester or nylon, making it an accessible option for casual gym-goers who train occasionally. While cotton doesn’t rank among the best type of underwear for gym workouts from a performance standpoint, it still serves blokes who prioritise natural materials and don’t generate excessive sweat during moderate training sessions. The familiar feel and lower price point make cotton a starting option before you invest in technical performance underwear.
Why it works in the gym
Cotton provides decent breathability during light to moderate training because the natural fibres allow some air circulation against your skin. For short gym sessions under 45 minutes or strength training with longer rest periods, cotton manages basic moisture adequately without causing immediate discomfort. The soft texture feels gentle against your skin and won’t irritate sensitive areas during low-intensity exercises like stretching, yoga, or walking on the treadmill.
Cotton’s natural composition makes it suitable for blokes with sensitive skin who react poorly to synthetic fabrics or chemical treatments.
Best for
Beginners who train casually two to three times weekly will find cotton boxer briefs sufficient for their needs. If you’re doing light weights, gentle cardio, or flexibility work without breaking a heavy sweat, cotton handles these low-intensity sessions without major issues.
Watch-outs
Cotton absorbs and retains moisture instead of wicking it away, which means the fabric becomes heavy and stays wet during intense training. This moisture retention creates the perfect environment for chafing and bacterial growth.
Typical price in Australia
Basic cotton boxer briefs cost $15 to $25 per pair in Australia. Department store brands start around $12, while premium cotton versions reach $20-25. Budget $35 to $60 for a three-pack from mainstream clothing retailers.
12. Lined training shorts with no underwear
Lined training shorts eliminate underwear entirely by incorporating a built-in mesh or compression liner directly into the garment. This approach removes an entire layer of fabric from your workout setup, creating maximum airflow and reducing the bulk that comes from wearing separate underwear beneath your shorts. While going commando in lined shorts seems unconventional when discussing the best type of underwear for gym workouts, many runners and athletes prefer this streamlined option because it cuts weight, eliminates visible lines, and prevents the friction that occurs when two layers of fabric move against each other during intense training.
Why it works in the gym
The integrated liner provides adequate support and coverage without requiring separate underwear, which means less fabric touching your skin and fewer layers trapping heat. You’ll move more freely during sprints, jumps, and agility drills because nothing bunches or shifts between your skin and your shorts. The single-layer design allows sweat to evaporate faster since moisture doesn’t get trapped between underwear and shorts, keeping you drier throughout your session.
Removing the underwear layer entirely eliminates friction between garments, which prevents the specific type of chafing that develops when two fabrics rub together during repetitive movements.
Best for
Distance runners and track athletes benefit most from lined shorts because the lightweight design reduces drag and prevents the added weight of sweat-soaked underwear during long runs. If you compete in races or log serious mileage, eliminating unnecessary fabric improves comfort over extended efforts.
Blokes who experience chafing between fabric layers will appreciate how a single liner prevents the double-friction problem that occurs with traditional underwear and shorts combinations.
Watch-outs
You need to wash lined shorts after every single session because the liner sits directly against your skin without a protective underwear barrier. Bacteria and odour build up faster than with traditional setups.
The built-in liner typically offers less support than proper underwear, so high-impact activities or heavy lifting might feel uncomfortable without additional structure.
Typical price in Australia
Quality lined training shorts range from $40 to $80 per pair in Australia. Running-specific brands with compression liners cost $60-75, while basic mesh-lined versions start around $35. Budget $110 to $200 for three pairs from established athletic brands.
What to wear next time you train
Your choice of gym underwear directly impacts every workout you complete, from your comfort during warm-ups to your performance during peak efforts. The best type of underwear for gym workouts depends on your specific training style, body type, and personal preferences, but pouch boxer briefs consistently deliver the combination of support, breathability, and chafing prevention that most blokes need during intense sessions. You’ve now got a clear picture of what works for different training scenarios, from compression styles for heavy lifting to mesh panels for hot conditions.
Stop settling for underwear that holds you back or leaves you dealing with irritation after every leg day. If you’re ready to eliminate chafing and experience proper anatomical support, check out SLY Collective’s bamboo pouch boxer briefs. The temperature-regulating fabric and built-in pouch design address the specific problems that plague traditional gym underwear, and you’ll notice the difference from your first squat. Your training deserves gear that actually supports your performance instead of fighting against it.
