External Catheter for convenience

I went kayaking today for four hours. I wore a silicone external catheter & leg bag under the paddling suit; I urinated several times & just drained the bag into the bottom of the boat. I've read about divers, boaters, stadium goers, long distance trucker who wear one to pee when impossible to get to a bathroom. I have photos in the gallery of me wearing external catheters. http://www.zity.biz/index.php?mx=profile;ox=contrib-albums;u=49624
