A wetsuit or wet suit is a garment sometimes worn by swimmers,
surfers and divers for warmth. It may be made of rubber, lycra
or neoprene. It typically covers the whole body except the head,
hands and feet and is usually quite close-fitting, acting like a
catsuit. It differs from a drysuit because water can get between
the garment and the person's skin, forming an insulating layer.
