The Under Armour Qualifier Mens 1/2 Zip Shirt comes in a fitted, next-to-skin fit without the squeeze, along with HeatGear fabric which is ultra-soft & smooth for extreme comfort with very little weight. UA Microthread technology in the fabric dries faster, won't cling to you, won't chafe and stretches without absorbing sweat. Mesh underarm panels for strategic ventilation. Woven overlay on the shoulders & chest provides added durability. Four-way stretch construction moves better in every direction. Material wicks sweat & dries really fast. Generous, �-zip front makes for easy layering. Dropped, shaped hem for enhanced coverage. Built-in thumbholes help keep sleeves in place.
