Question re my 7 mil farmer john---Suppose I cut a flap opening in the bottom part. Since the top part also covers the area in question, would the flap cause much heat loss? I'm not thinking of using said flap during a dive, but it would eliminate taking the top & bottom down to pee during the SI (a MUST) then squeezing back into a wet wetsuit--difficult in warm weather, brutal incold weather. Pee valve or drysuit zipper are out, as they cost as much as the used wetsuit did.
If you were so inclined to use a pee valve in a wetsuit, you really only need a section of tubing to connect to the cath, no expensive valves are needed. The pressure inside and outside is the same.
