My son used this at swimming school because he gets cold easily. I'm selling it because he's outgrown it. It's designed to fit snugly to keep you warm, so it might feel small. It's not made of thin, rash guard-like material, but rather a thicker, wetsuit-like fabric. He stopped saying he was cold after wearing this. He wore his swimsuit over this, so there are no tears, but there are some fold marks. Please understand that this is a used item.
