The Diamondback Bush Pilot helmet offers tested protection in a no-nonsense package. The durable, in-moulded polycarbonate shell helps to aid in resisting frication if an impact occurs. The other benefit is that it adds a light-weight barrier that will protect the ABS liner from wear & tear. Among that you get a dial-fit adjust system for a precise fit, and 18 cooling vents to help keep you cool on those long-haul, trail-rides.
