Drop into banked corners, and roll flowy singletrack with confidence. Designed for those who embrace speed, the Smith Payroll mountain bike helmet offers complete coverage for enduro, trail and E-MTB use. The lightweight design is E-bike certified, which tests helmets at higher speeds than traditional bike helmet certifications. Zonal KOROYDA(R) and MipsA(R) impact technology mean that you can focus on the trail. Our VaporFit(TM) system lets you adjust the helmet on the fly, and the MipsA(R) layer is integrated with the fit system for a snug, cohesive fit that feels great all day. Generous vents with internal air channels keep you cool while climbing and focused on the descent with fog-free lenses. The three-position visor accommodates sunglasses or goggles between laps or when the sun finally drops below the horizon.
