Ready to step up your trail-riding game, Bell's Stoker helmet flaunts plenty of substance with style. This wonder helmet sports Bell's Fusion In-Mold Microshell for excellent strength and low weight, plus their SpeedDial fit system and Cam-lock straps for an easy to adjust fit that won't shake loose no matter how rough the trail. Thirteen vents and four brow ports keep air flowing so you stay cool, and the adjustable visor is goggle compatible. With the MIPS Brain Protection System, the shell and the liner are separated by a low friction layer. When subjected to an angled impact, the low friction layer allows the helmet to slide relative to the head, thus reducing deceleration injuries to the brain.
