Like its siblings in the Cyclone line of packs and bags, the Dakine Cyclone Thruster board bag features tough, waterproof Cordura(R) fabric on its top panel, keeping weather and debris from damaging your board. Slim enough for daily use, but tough enough for travel's abuse, it boasts 360 degrees of 8mm foam padding and a heavy-duty YKK(R) zipper. And with new, heat-reflective Silver Energy Shield Lite, your board will stay cool in the sun, meaning you won't have to pull it out of a puddle of wax when you arrive at the spot.
