HeatGear® Armour is our original performance baselayer—the layer you put on first and take off last, like this tank top for women. Sweat gets wicked away and then dries fast to keep you cool. Super-soft pinhole mesh delivers superior breathability without sacrificing coverage. Material wicks sweat & dries really fast. 4-way stretch construction moves better in every direction. Rolled forward flatlock seams deliver a comfortable, chafe-free fit. Classic racer back. Shaped drop-tail hem offers superior back coverage. Fitted: Streamlined fit that's not too tight or too loose. 94% Polyester/6% Elastane.
