Climb X Double X Crash Pad. We made the largest Crash Pads possible that could still fit shipping standards. The XX is constructed with burly outer material, Aircraft Grade Aluminum buckles, and dual density foam for a longer life and safer landings. Our dual straps allow you to carry the pad like a backpack on the approach, or pick it up like a duffle to move over to the next problem. No more worrying about twisted ankles from stacked pads since Climb X pads can be velcroed together to create a larger, safer, solid, landing area. At the end of a long session, go ahead and strap the pad into couch mode and chill round the fire.
