A team favorite from big mountain skiers to park riders, the Jackson™ offers the protection of Mips® with minimalist venting for a clean, timeless design.
The modern profile of the new Jackson helmet utilizes the new Passive Aggressive Venting system, inspired by the aerodynamic airflow of high-end autos. The discreet yet powerful system effectively manages airflow and temperature while in-motion riding, hiking or standing static. The overall look is finished with a slight brim and subtle lines for Seamless Compatibility with Giro goggles. The Jackson Mips® technology, an ultra-lightweight construction and the dialed In Form 2 Fit system allows you to confidently focus on the terrain ahead. Leave no line untracked in the new ultimate freeride helmet.
