Sports board (15) comprising an elongated expanded closed-cell polyolefin foam core (16) having a core thickness and opposed surfaces (18, 19), a first polyolefin sheet layer (23) having a thickness less than the core thickness and having an inner surface (25) and an outer surface (24), an intermediate metallocene-based polyolefin layer (20) having an inner surface (22) and an outer surface (21) and a thickness less than the core thickness, the intermediate layer bonded on its inner surface to the core and bonded on its outer surface to the inner surface of the first layer. The intermediate layer may comprise an ethylene-alpha olefin copolymer and may comprise a copolymer of ethylene and octene.
