Arena Tough Suit Training Swimsuit Competition Swimwear Size M This is an Arena training swimsuit with a cute back cut. Made of chlorine-resistant Tough Suit material, it has a sturdy fabric that lasts. It has been worn a few times and is in beautiful condition with no noticeable damage, stretching of the elastic, or fabric. I have two of the same swimsuit that I like, and I don't have many opportunities to wear them, so I'm selling this one. Please understand that this is a used item stored at home. I will pack it carefully and ship it. Arena Mizuno Speedo Masters Swimming Athlete Development Competition Training Swimsuit
