The Soma AirBag is a $150 inflatable surfboard bag constructed with 600-denier ballistic polyester coated with polyester vinyl chloride (PVC) and 1000-denier PVC along the tail, nose and rail. Inside are individual columns of air intended to help disperse the force of some pretty intense-looking impacts.
Soma is currently sold out until the end of June, but I'm told the next iteration will boast "extra protection" including dual-density foam and side stabilizers to help maintain air pressure. Soma says the new bag will be able to withstand a 2-story drop.
As soon as they send me one, we'll find out.
