I purchased this here and used it for competitions and practice. I don't remember how many times I wore it. It's an arena competitive swimming racing swimsuit. It has the Fina mark. The Fina mark is slightly cracked. Please check the photos. It's size M. Please understand that this is a used item before purchasing. I'm selling it because I haven't had a chance to wear it recently, as I've been using other swimsuits. It's been stored by a beginner, so please refrain from purchasing if you are sensitive to such things.
