Nike STASH DUFF The Nike STASH DUFF women's sports bag is lightweight and foldable so it gives you storage when you need it and folds away when you don't. You can put small items in the front zipper pocket and when you turn it inside out, you can quickly pack the entire sports bag into the pocket. It's big enough for clothes and shoes to change into so it's perfect for the gym and sleepovers. At least 65% of the product is made of recycled polyester. Nike STASH DUFF
