Finally, a nice running shirt for men awarding it all to you! You may not be a champion....but you are surely the world's okayest Runner. LOL. Our quick try 100% polyester is our ultimate shirt to wear on race day, it is soft and light weight. However we also offer a blended fabric one, with 60% polyester and 40% cotton, again light weight and ultra soft. Comfortable on the run and on post run.
