Wear Dive Skins Underneath Wetsuits

Dive skins are for warm-water diving. Some people even wear skins on cold-weather beaches, or at indoor swimming pools.
Made from Lycra or Spandex, dive skins aren't designed to keep divers warm, but they are helpful in protecting skin from cuts and scrapes. Some divers wear thin dive skins underneath their scuba suits.
Dive skins can get damaged from the salt and sun, so it is a good idea to always wash your dive skin in freshwater, hang it up, and let it dry. Don't throw it in the dryer; the heat will destroy the material. Do not try to store it wet either, or mildew will grow on the material.
