Choosing the right underwear for the gym can make a bigger difference than most people realise. During exercise, your body generates heat, moisture, and constant movement. If your underwear doesn't provide the right support or manage perspiration effectively, it can quickly become uncomfortable.
The best gym underwear should stay in place, provide reliable support, reduce friction, and keep you cool throughout your workout.
Whether you're lifting weights, running, cycling, or training for sport, this guide explains what to look for and which styles perform best.
Quick Answer
The best underwear for the gym is supportive, breathable, moisture-wicking, and stays securely in place throughout your workout. For most men, supportive briefs, trunks, or jockstraps made from performance fabrics provide the best combination of comfort and stability.

During exercise your underwear experiences more stress than almost any other piece of clothing.
Poor-quality underwear can lead to:
- Chafing
- Excess sweating
- Constant adjusting
- Reduced support
- Discomfort during movement
Good gym underwear should become something you don't notice. It moves with your body, supports you naturally, and allows you to focus on your workout. Read more about Why Does Underwear Ride Up? Causes, Fixes & What to Wear Instead
What Makes Good Gym Underwear?
Support
Support should always come first.
During movement, unnecessary bouncing or shifting can quickly become uncomfortable.
Look for underwear with engineered support that keeps everything comfortably in place without excessive compression.

Breathability
Heat builds quickly during exercise.
Breathable fabrics allow air to circulate more effectively, helping regulate temperature throughout your workout.
Moisture Management
Sweating is unavoidable.
The right fabric moves moisture away from your skin, helping you stay drier for longer.
Stretch
Exercise requires unrestricted movement.
Your underwear should stretch naturally without losing its shape or becoming loose over time.
Durability
Gym underwear is washed frequently.
Choose quality fabrics and construction that can withstand regular wear without losing support or elasticity.
Which Underwear Style Is Best?
Briefs
Briefs remain one of the best choices for strength training.
They provide excellent support while allowing complete freedom of movement.
Best for:
- Weightlifting
- CrossFit
- Functional fitness
- Everyday training
Trunks
Trunks offer slightly more coverage while maintaining good support.
They're ideal for men who prefer a little extra fabric around the upper thigh.
Best for:
- General gym sessions

Jockstraps
For maximum support during high-impact activities, jockstraps remain one of the strongest options.
They provide excellent stability while allowing increased ventilation.

Which Fabric Is Best?
Performance fabrics generally outperform traditional cotton during exercise.
Look for fabrics that are:
- Moisture-wicking
- Lightweight
- Breathable
- Quick drying
- Stretchable
Cotton remains comfortable for everyday wear but tends to retain moisture during intense exercise.
Common Mistakes
Wearing Cotton During Intense Training
Cotton absorbs perspiration and dries more slowly than technical fabrics.
Wearing Underwear That's Too Loose
Loose underwear allows unnecessary movement, increasing friction and reducing support.
Wearing Underwear That's Too Tight
Excessive compression can restrict comfort and reduce airflow.
Support should never come at the expense of movement. If you're still unsure, here is a guide on How Should Men's Underwear Fit.
Ignoring Fit
Even premium underwear won't perform well if the size is incorrect.
Always choose the correct size according to the manufacturer's guide.
