No matter the trail, get after it with confidence in the Smith Engage mountain bike helmet. MIPS® Brain Protection System helps reduce angled impact forces in the event of a crash, while the VaporFit™ dial adjustment and extended back coverage provide a locked-in feel. On hot days or exposed climbs, 20 fixed vents and the AirEvac™ ventilation system keep you cool and comfortable. Channels on the front make it easy to stow eyewear and a two-position visor rotates up for on-the-go goggle storage.
