HeatGear® 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 matter what. Super-light HeatGear® fabric delivers superior coverage without weighing you down. This garment is made with material that wicks sweat & dries really fast. Its 4-way stretch material moves better in every direction, and ergonomic flatlock seams deliver a comfortable, chafe-free fit. The high-rise UA No-Slip Waistband provides optimal coverage & support that stays put with every move you make. It also features a side drop-in pocket.
