Must have in cockpit of kayak
Whether play boating, river running, or longer self support trips a good sponge is a must have to keeping the boat dry and clean. This sponge works fine. I find the trick is to keep it in a small mesh bag attached with a carabiner. That way it is always handy, you won't loose it as you don't have to take it out of the boat. Just find some old mesh bag (if you buy boating gear it often comes in mesh bags you'll never use again), cut it to size, sew it up, and you're there!
