Under Armour Seamless Half-Zip Top

Using levels of mesh mapped to your body, you get ventilation where you need it, plus the comfort of fewer seams. It's pretty much the most comfortable thing you'll ever train in.

Constructed using soft knit fabric with engineered mesh ventilation, mapped to the places you need it most, the Under Armour Seamless Half-Zip Top is extremely breathable and comfortable. The top features nearly sew-free construction to eliminate chafing and 4-way stretch construction moves better in every direction. This combination allows you to move freely without worry of irritation or material holding you back. The material works to wick sweat as it is produced and dries really fast to keep you dry and comfortable during exercise. The generous half-zip front makes this piece easy to layer.
