Closed Cell Foam is great for custom outfitting your kayak to fit certain needs. Whether it is making a custom transducer pad, carving new hip pads for your sit inside kayak, adding more flotation to your kayak, or for re-enforcing the deck of your kayak to be able to take a heavier load, the Closed Cell Foam can do it all.
Nice dense foam. I used this for my seat cushion and works great. I left it this size and cushions my hips also.
Great stuff, best price!
