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 KOROYD and Mips impact technology mean that you can focus on the trail. Our VaporFit system lets you adjust the helmet on the fly, and the Mips 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.Product Details:Protection:Complete KOROYD coverage for lightweight, energy-absorbing and ventilated impact protectionMips Brain Protection System reduces rotational forces caused by angled impacts to the headIntegrated skeletal structure creates a roll cage for added strength and impact protectionNTA8776 E-bike, CPSC, CE EN 1078 and AS/NZS2063 certifiedComplies with U.S. CPSC Safety Standard for Bicycle Helmets for Persons Age 5 and OlderFit / Integration:Designed for ultimate integration with Smith performance eyewear and goggles for maximum comfort, venting and storage convenienceAirEvac ventilation system integrates with Smith goggles and eyewear for fog-free lensesVaporFit dial adjustment system offers 270-degree fit adjustment with the turn of a dialFeatures:19 fixed vents for consistent airflowThree-position adjustable visorIonic+ antimicrobial lining offers sweat-activated odor controlLightweight, low-bulk single-layer webbingY-strap divider keeps helmet straps flat and close to the faceFront eyewear storage channelsWeight (Size M, Mips): 14 oz / 400 g
