The Harmony Super sponge will help keep the inside of your boat dry. This synthetic sponge has a cellulose cover, absorbs up to a liter of water, is resistant to mildew, and is machine washable. It's durable, compact and features a handy tie-in tether sewn to the corner. It can be used in conjunction with a bilge pump on on its own.
This is my second Harmony Super Sponge, and it is a high quality item that is easy to use and maintain. A must have.
Great product, asorbs water fast
