Product Details A quiver of one. The Holt helmet serves up all-season certification, so you can reach for one helmet to cover you from terrain park to skate park or backcountry kicker. Smith's bombshell construction means it holds up to the hard knocks of living the life. Plenty of vents keep the air flowing and your goggles fog-free.
