EDIT ALERT:
I response to CRP's question I was examing my shorts. Neoprene cement does not do as well on the spandex as it does on wetsuit/neoprene. Plent of companies make 1 mil wetsuit shorts. Use those.
I will probably stitch these. I Have had no problems as the pockets are holding fine in shear and withdrawal. However, I think I can "peal" them if I try. Unaccpetable.
Got the shorts from a surf shop. Wear them under board shorts. Neoprene, about (less than) 1 mil I guess. I originally was going to try biker shorts, but I had these.
I bought the pockets from Phil Ellis' Divesports.com. They were less than $20.00. I have pockets glued on 2 wetsuits and decided it was getting rediculous when I was looking for another suit.
These I can wear without a wetsuit, with a shorty etc.
I have installed 6 pockets so far and have it down to a science, so if you decide to do it PM me.
Phil has instructions for doing it on his web site, but I like my method better.
EDIT: Just looked at the shorts. These particular ones are spandex and polypropylene.
