Scuba Divers wear wetsuits for the purpose of staying warm and protection. Wetsuits are named wetsuits because they get you wet. Water goes into the wetsuit and gets trapped. This trapped water is then heated up by your body by the escaping heat. This in turn keeps you warm. Also you know how when washing dishes your hands get soft. Well that happens to your body so rubbing against anything down there will for the most part cut you. The suits keep you protected.
