I spent the day looking for a waterproof bag to add to a gift of gym towels. Ended up buying a dry bag used for hiking/canoeing. The lo and behold I found a pattern for a bag for wet bathing suits which would have worked well and been waaaaay cheaper.
Might be a good little stocking stuffer. It uses PUL fabric.
