A highly absorbent sponge with a 100% viscose fabric cover that holds 32 oz. of water. Sit-In-Side Paddlers like a sponge, and some Sit-On-Top paddlers can benefit from a sponge too. Not only will this sponge help dry out your seat, but it will mop up bilge water in side your kayak too. Featuring the Seaward logo.
