The Smith Engage MIPS® Mountain Bike Helmet offers the protection, comfort and style that you need in the trail. This helmet is equipped with MIPS® Brain Protection System that reduces rotational forces caused by angled impacts to the head, while its Zonal Koroyd® complements MIPS® for energy-absorbing impact protection in the event of a crash. On hot days or exposed climbs, 21 fixed vents and the AirEvac ventilation system keep you cool and comfortable, while a dial adjustable fit and extended back coverage provide a locked-in feel, along with its channels on the front that make it easy to stow eyewear and a two-position visor rotates up for on-the-go goggle storage. No matter the trail, get after it with confidence in the Smith Engage MIPS® Mountain Bike Helmet!
