Nike jersey made of polyester! It's thin and easy to use, perfect for running and sports! I bought it a year ago, but I'm selling it because I bought a new one. *Please refrain from purchasing if you are overly sensitive. *Returns and exchanges are not accepted. *If you live on a remote island, please be sure to comment.
