Mixing the best of fashion and function, the Y-3 Running Short Sleeve Tee is built for movement. It's woven from a recycled polyester fabric that has built-in stretch for easy wear. A polyurethane coating helps wick away water, and a crewneck keeps the fit feeling right. Side slits on the droptail hem open up the freedom to move. The finishing touch: Yohji Yamamoto's signature across the back in a reflective print that stands out when light is low.Made with a series of recycled materials, and at least 70% recycled content, this product represents just one of our solutions to help end plastic waste.
