I've been thinking that someday it would be nice to swim again but wonder if it's going to be too much trouble. I searched for "waterproof ostomy cover for swimming" on Amazon but I'm not sure I saw anything that's right for me. I have a big waist and wear size 3x-4x pants. Does anybody who's large-waisted swim? I'd like a product that keeps my ostomy pouch and wafer dry while swimming.
