Arbor Fish Koa Longboard Deck 2009: A compact pin, the Arbor Fish Koa was designed with a hyper-extended wheelbase, timeless teardrop shape, and concave profile to provide both carve and downhill function. Built from 7-plys of sustainably sourced Hardrock Maple and a finish ply of beautiful Hawaiian Koa wood, the Arbor Fish Koa Longboard is durable, lightweight and friend to Mother Nature.
