This is the New Balance Cooling Workout T-shirt. There are no odors, stains, or tears. Worn once for casual purposes, not for a physical workout, I list it because I bought it and didn't find it helpful for what I intended to use it for. Up your cool factor. The men's New Balance Ice Short Sleeve Tee helps keep you cool and dry as things heat up, thanks to sweat-activated NB Ice fabric. Flattering seams, back vents, and underarm gussets help ensure your workout goes smoothly from start to finish. - Shell: 100% polyester. - Lining: 91% polyester, 9% elastane. Get your fill of cool with NB Ice. Not only does it wick away moisture, but its Nano Aqua Chem treatment blocks the sun's infrared rays while Xylitol reacts to maximize the cooling effect further. NB Ice is designed to help keep you cool and dry when things heat up. Athletic fit built to skim your chest, waist and hip - perfect for active movement with a fit that's not too tight. - Underarm gussets. - Mesh insets. - Reflective logo and trims
