HeatGear is Under Armour's original performance baselayer - the one you put on first and take off last. This sleeveless compression muscle top is designed with a mock neck and ergonomically keeps seams off high abrasion areas. The fabric fits like a second skin, wicks sweat and stretches so you can move no matter what. Stretch-mesh panels at the sides and back deliver strategic ventilation. Write-in locker tag on back of neck for your name or number.
