Do You Need Different Underwear for Different Sports?

Quick answer

Yes, most guys benefit from more than one pair. A low-rise sports brief handles running, gym sessions and team sports well because it holds everything in place without excess fabric. A jockstrap suits high-sweat, high-movement days where you want airflow and minimal coverage. A thong is the pick for cycling or long wear under tight shorts where seams and bunching bother you most. Match the cut to the sport, not the other way around.

Most underwear advice treats training as one single activity. It isn't. A 10km run, a heavy squat session, a two-hour ride and a weekend football match all move your body differently, and the underwear that feels great for one can chafe, ride up or lose support in another.

The good news is you don't need a drawer full of specialist gear. Three cuts cover almost everything: a brief, a jockstrap and a thong. Below is how they compare on the details that actually matter during sport, plus how to choose based on the way you train.

What actually changes between sports

Three things separate one sport from another when it comes to underwear: how much you move, how much you sweat, and how tight your outer layer sits. Running and team sports involve repeated hip flexion and a lot of fabric movement, so a stable, low-rise cut that stays put matters more than anything else. Cycling is the opposite problem: you sit still for long stretches, so pressure points and seams become the enemy.

Gym training sits somewhere in between. Lifting involves less continuous motion but more bracing, squatting and stretching, which is where a cut that holds its shape and doesn't dig in earns its place. Once you know which of these three patterns your training follows, the cut choice becomes fairly obvious.

• High movement plus high sweat: prioritise a secure waistband and quick-dry fabric.
• Long seated sessions: prioritise minimal seams and a cut that won't bunch.
• Mixed training weeks: two or three cuts will cover you better than one.

Sports brief vs jockstrap: the core trade-off

A sports brief gives you full back coverage with a low-rise cut and a wide waistband. The Icon Sports Brief | New Fit - Navy uses a 4cm metallic waistband and a quick-dry modal blend, with cut-out sides for airflow. That combination keeps the brief locked in place during running and team sports while still letting heat escape. If you want one pair that handles most training days, this is the safer starting point.

A jockstrap flips the priorities. The Score Sheer Wide Cut Jockstrap - Gunmetal uses a solid fabric front pouch with sheer inserts through the sides and back, plus soft leg straps that are designed not to dig in. You get more airflow and less fabric against the skin, which many guys prefer for intense sweat sessions. The trade-off is coverage: the back is open, so it suits sport and layering rather than all-day wear under loose clothing.

• Choose a brief when you want support plus full coverage in one piece.
• Choose a jockstrap when airflow and minimal fabric matter more than back coverage.
• Both work for running and gym work; the jockstrap wins on heat, the brief wins on versatility.

Where a thong fits into sport

A thong sounds like the least practical option until you ride a bike or wear tight compression shorts. The Glide Micro Thong - Zest pairs a 1cm waistband with a minimal cut and a soft recycled fabrication, so there is very little material to crease or rub. On a long ride, that lack of bulk under padded shorts is a genuine comfort advantage rather than a gimmick.

The limitation is support. A thong holds you in place at the front but offers no back coverage and less overall stability than a brief, so it is a poor fit for stop-start sports like football or basketball. Treat it as a specialist piece for cycling and long seated sessions, not as your default training underwear.

• Best used under tight or padded outer layers where seams would otherwise rub.
• Not the right pick for sports with lots of direction changes and jumping.

Fabric and waistband details that decide comfort

Fabric matters as much as cut. Quick-dry modal and stretch blends move sweat away and return to shape, which is why they show up in sport-focused pieces. The Team Cotton Brief - Ecru takes the opposite approach with a ribbed cotton-stretch fabric and a 2.5cm waistband. It is exceptionally comfortable for everyday wear and light training, but cotton holds moisture longer, so it is not the first choice for a heavy sweat session.

Waistband width is the other quiet factor. A wider band spreads pressure and stays put during movement, which helps in running and team sports. A narrower band feels lighter and less noticeable, which suits cycling and low-impact days. Neither is better in the abstract; they solve different problems.

• Quick-dry stretch fabrics for high-sweat sessions; cotton blends for low-intensity days.
• Wider waistbands for stability during running and court sports.
• Narrower waistbands for seated sports and minimal-feel wear.

Building a small rotation that covers your week

You do not need a separate pair for every activity. A practical rotation is two briefs for running, gym and team sports, one jockstrap for the hottest or most movement-heavy sessions, and one thong for cycling or long days in tight shorts. That is four pieces covering essentially every training pattern.

If you are starting from scratch, buy the brief first. It is the most versatile cut and the easiest to wear across multiple sports. Add the jockstrap or thong once you know which sessions leave you adjusting, chafing or overheating, because that specific problem tells you exactly which cut to reach for next.

• Start with a brief, then add a specialist cut based on a real problem you notice.
• Wash sport underwear after every session to protect stretch and shape.

Trade-offs by sport

• Running and team sports: A low-rise sports brief with a wide waistband gives the most stable fit and full coverage through repeated movement. Best all-round choice if you only buy one pair.
• High-sweat gym sessions: A jockstrap reduces fabric against the skin and increases airflow, but leaves the back uncovered. Great for the session, less practical for all-day wear afterwards.
• Cycling and seated sessions: A thong removes bulk and seams under padded or tight shorts, but offers less overall support and no back coverage. A specialist pick rather than a daily default.

Product facts at a glance

• Icon Sports Brief | New Fit - Navy: Sports brief cut with cut-out sides, a 4cm metallic waistband and quick-dry modal fabrication (95% rayon, 5% spandex). The wide band and secure cut suit running, gym work and team sports where you want full coverage that stays in place.
• Score Sheer Wide Cut Jockstrap - Gunmetal: Solid fabric front pouch with sheer inserts through the sides and back, soft leg straps and quick-dry 4-way stretch fabric. More airflow and less fabric contact make it a strong pick for high-sweat sessions, with the trade-off of an open back.
• Glide Micro Thong - Zest: Minimal thong cut with a 1cm waistband and soft recycled fabrication. Very little material to bunch or rub, which helps under padded cycling shorts or tight compression layers.
• Team Cotton Brief - Ecru: Ribbed cotton-stretch fabrication with a 2.5cm waistband and low-rise cut. Comfortable for everyday wear and light activity, but cotton retains moisture longer than quick-dry fabrics.

Which should you buy?

Best for

• Runners and team-sport players who want one stable, full-coverage pair
• Guys who train in hot conditions and want maximum airflow
• Cyclists and anyone wearing tight or padded shorts for long periods

Not for

• Anyone who wants a single pair to cover every sport and everyday wear
• Buyers who prefer full back coverage in every session
• Heavy sweaters who want to stay in cotton all day

Match the cut to the way you move: a brief for most training, a jockstrap for heat and airflow, a thong for long seated sessions. Two or three pairs cover your whole week, and each one earns its place by solving a specific problem.
