Big & Tall Knit Sports Underwear Activewear

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.

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.

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.
