I'm not afraid to pee off the back of the boat during surface intervals or just before the first dive. I'm not a tech diver (yet?) so I'm never under for more than an hour. All of that being said, I was turned off by the word "catheter". I assumed that meant internal insertion. I didn't realize there was an external option. This intrigues me but I'm still on the fence without doing dives over an hour. Thank you for that and the vote of confidence for the plastic zip. Having tried on a suit with a brass zipper, I can see where the flexibility and easy of movement from a plastic zipper would be a good thing.
Be glad you’re not a gal. Look up the She-P. It’s arts and crafts time when we go to put it on. Lotsa glue. I also use Rock Tape to help keep it on. Can you imagine a guy using Rock Tape on his nether regions? Ain’t gonna happen! The Rock Tape is more comfortable than the two thong undies (one on each side) the manufacturer recommends (wedgies are uncomfortable while diving!)
