HeatGear® Armour is our original performance baselayer—the one you put on first and take off last. So we made it extra comfortable by wicking sweat and stretching so you can move. No athlete can go without it. Super-light HeatGear® fabric delivers superior coverage without weighing you down. Strategic mesh panels for added ventilation where you need it. Material wicks sweat & dries really fast. Ergonomic design keeps seams off high abrasion areas & increases durability. Wide, exposed elastic waistband with wordmark detail. Updated gusset design provides ultimate support & comfort. Drop-in Strength Pocket™ on right side for easy storage. Inseam: 9"". No fly. Compression: Ultra-tight, second-skin fit. 84% Polyester/16% Elastane.
