Under Armour is taking a 24-hour, 365-day holistic approach to the life of a runner with its release this week of  UA Rush, its newest performance apparel line, designed to be worn at the time of sweat. This scientifically engineered fabric promotes improved performance and energy return. In simplified terms, UA Rush is intended to provide the same benefits to the body as an infrared sauna. During a run, the body emits energy in the form of heat — Rush apparel reflects it back to the wearer, thus recycling the body’s energy.

The key run pieces in the collection are the UA Rush Run HeatGear tights and short sleeve shirts. The mineral-infused fabric absorbs the energy the body emits and reflects it back into tissues and muscles, promoting more speed, more strength and more stamina.

The Rush collection is now available at UA.com, in UA Brand Houses worldwide and with select retailers.
