Designed with feedback from Fox's Elite race team! The Launch Pro D3O utilises anatomically designed panels and construction to ensure they are comfortable throughout your ride. Combined with breathable Ariaprene neoprene and a moisture-wicking back panel, these pads will provide outstanding ventilation considering the amount of protection they offer. The biggest feature is the D3O padding! D3O remains flexible in its normal state but hardens instantaneously when you impact an object.

They remain comfortable enough to for longer riders, yet give you class leading protection on gnarly descents.
