New Balance Impact Run Women's T-ShirtDesigned for impressive cooling, the Impact Run Short Sleeve from New Balance features fast-drying NB ICEx technology and a breathable mesh fabric to help keep you cool and comfortable through any run. This women's short sleeve top also includes reflective details for added style. Enriched with NB ICEx technology, the Impact Run T-Shirt works to wick sweat away from the skin onto the outer layer of the garment where it can be evaporated, leaving you feeling cool, dry and light on your feet as you hike up the final peak or push through the last mile of your run. The poly knit mesh fabric increases breathability by allowing cool air to permeate and hot, muggy air to escape, helping to regulate body temperature and prevent an intolerable build-up of heat. In an athletic fit, the Impact Run T-Shirt is built to skim your chest, waist and hip - perfect for active movement with a fit that's not too tight and not too loose. Lastly, reflective elements help to improve visibility in low light conditions. Sustainability - 95% Recycled Polyester.
