HeatGear® Armour is our original performance base layer - the one you put on first and last off. So we made them extra comfortable by wicking sweat and stretching so you can move no matter what. Super-lightweight HeatGear® fabric provides excellent coverage without weighing you down. Strategic mesh panels for extra ventilation where you need it. The material wicks sweat and dries very quickly. Ergonomic design keeps seams away from heavily worn areas and increases durability. Wide, exposed elastic waistband with wordmark detail. Updated gusset design provides ultimate support and comfort. Drop-in Strength Pocket™ on the right side for easy storage. Inseam 28". No fly compression: ultra-tight, like a second skin. 84% polyester, 16% elastane
