Yeah sure it,s funny .But seriously......I know there is dry-suits available with pee valves . But what about wet-suits..I,m a new diver and still using rented skins or dive shop loaners. So you can imagine my reaction when our instructor suggested we shound pee if we have to ..YIKES STRIPES ..Im goin to buy my own suit soon. Any suggestions.. I live in Montreal and it can get cold ,still I plan to do mostly warm water dives.
