This limited edition BioBoard™ is made with FlaxFlex™ technology that harnesses the shock-absorbing power of natural flax to ensure precision edge control while making board chatter a thing of the past. Our riders report that the flax fiber gives the board better pop and responsiveness than anything they've ridden - and with our money back guarantee, you can try it yourself for 30 days and and return it for a full refund if not completely satisfied!
