Who doesn't know the classic air-filled swimming cap? When you look at the studded rubber surface, you can't help but think of your first attempts at swimming. With a zipper, it becomes a toiletry bag, a cosmetic bag or a case for miscellaneous items. You don't want to swim with it anymore, but take it to the swimming pool? Gladly!
