It's been many years since I used a boogie board but I got this one for a trip to the ocean in a few weeks with my grandson who has never been to the beach. It is a high quality product and I think it will hold up well when coming in to the shore with rocks and shells clawing at it on the ocean bottomIt feels firm to the touch and the leash is coiled which I like a lot.Expanded Polystyrene (EPS) coreApprox. 37"x19"Laminated plastic meshHDPE Slick bottom
