A
wetsuit is a garment, usually made of foamed
neoprene, which is worn by
surfers,
divers,
windsurfers,
canoeists, and others engaged in
water sports, providing
thermal insulation,
abrasion resistance and
buoyancy. The insulation properties depend on bubbles of gas enclosed within the material, which reduce its ability to
conduct heat. The bubbles also give the wetsuit a low
density, providing buoyancy in water.
