Check the listing for details. Child's Swimming Top. Condition: New. Listed at 7.00 USD. PLEASE READ. This is a very snug-fitting boys XL swimming top. I bought it for my son who was a large - it would fit him for his purposes when he was a size small. I believe that it is a competitive swim top for speed. If you are purchasing be aware that it will be a very tight fit or you could get it for your child who is a small or medium as a casual swim top.
