The evolution of coverage and performance for long-travel trail riding. As trail riding progresses, helmets have to evolve. The Feature starts with a new shape that combines a little more coverage than traditional helmets, with vents that radiate heat up and out of the helmet; perfect for climbing at lower speeds. And when the trail drops, out rugged In-Form fit system offers one-handed fit and stability adjustment, so you can dial-in the perfect feel and stay focused on the trail ahead.S: 51-55cmM: 55-59cmL: 59-63cm
