Under Armour Rush Seamless Compression T-Shirt No wasted energy, only more gains. The mineral-infused fabric takes the energy you give off when you work and reflects it back into your muscles, increasing blood flow and helping them to work harder. In a compression fit, the Rush Seamless Compression T-Shirt is ultra tight and provides a second skin fit. As your body emits energy, the mineral-infused fabric absorbs and reflects it back, improving endurance and performance. The soft knit fabric with engineered mesh ventilation mapped to the places you need it most provides excellent breathability, allowing cool air to permeate and hot air to escape. The nearly sew-free construction eliminates chafing and skin irritation, whilst the 4-way stretch construction moves better in every direction as your clothing choice should never inhibit your performance. The material wicks sweat away from the skin onto the outer layer of the garment where it can be evaporated, leaving you feeling cool, dry and comfortable.
