Explore Athletic Underwear For Men

For sports and exercise, your underwear can be your best partner. Special construction, fabrics, and innovative properties will keep you cool, comfortable, and supported through any kind of workout. From jockstraps to long johns, there are styles for everything you love to do. Here, you’ll find moisture-wicking, odor-resistant, and compression-enhanced designs that are built to go the distance with you.

Performance-Focused Fabrics and Fit

Typically, sports underwear is designed to be lightweight, non-chafing, and offer some sort of muscle support. Look for thermal properties that keep you warm in cold weather and help wick away moisture to keep you dry and cool during any sport. For many activities, you'll also want underwear that is form-fitting without restricting movement. There are so many styles available that you'll be able to create the complete sports underwear wardrobe! Styles include boxer briefs, boxers, jocks with contoured pouches for support, stretch trunks, compression shorts and men’s sport briefs.

Cold Weather Layers and Compression Gear

For cooler weather, we offer stretch leggings, often with functional fly-front. Skiers and snowboarders will appreciate classic long johns, many of which are constructed from soft stretch fabric and have contoured pouches. Serious athletes love compression shorts, which come in several lengths. Some are made of breathable mesh and come with a cup pocket. The four-way stretch provides muscle support for less fatigue and improved performance.

FAQs

What is the difference between athletic underwear and regular underwear?

Athletic undergarments are designed with moisture-wicking fabrics, stretch support, and minimal seams to reduce chafing during movement. Regular underwear may not offer the same breathability, support, or performance features.

Is athletic underwear worth it?

Yes. If you’re active, these underwear options help prevent irritation, overheating, and discomfort during workouts. They provide better support and can improve overall performance and recovery.

What are the benefits of sports underwear?

Underwear for sports keeps you cool, dry, and supported during activity. They reduce friction, support muscles, and adapt to movement, making them ideal for everything from daily workouts to outdoor adventures.

How tight should these underwear be?

It should feel snug but not restrictive. A proper fit ensures support and prevents chafing, while still allowing full range of motion. If it cuts in or rides up, try a different size or style.
