Mine is above my belt line. Been swimming, I just put some tape on to reduce the "bulge". Try some pink tape, I have found some 6" wide in the Edgepark catalog. I've tried some elastic brown-colored tape, but it didn't stick in the water.
My 3 year old niece asked me what that was, I told her it was a bandage from where the doctor fixed me. If anyone else has a problem, too bad.
First time I went swimming, I taped all the edges of the flange with 1" pink tape, then put the 6" pink tape across the bag (where it is above my swim trunks), then put the elastic-brown-colered tape over that. Didn't want to be too conspicious! The brown tape didn't stick in the water, so now I just use the pink tape on the outside. It stick to the bag pretty heavy, so after I swim I usually end up changing the whole pouch.
