  • Features

    • Spherical Technology allows the outer liner to rotate around the inner liner during a crash and also eliminates contact with a hard-plastic slip-plane
    • This ball-and-socket design, powered by Mips, helps redirect impact forces away from the brain by allowing the outer liner to rotate around the inner liner during a crash
    • It also eliminates contact with hard plastic or slip-planes against the skin
    • Progressive Layering provides dual-density foam liners designed to address high- and low-speed impacts for more comprehensive energy management
    • Structural integrity is bolstered by the translucent, shatter-resistant AURA reinforcing arch that runs throughout the helmet
    • Roc Loc® Trail Air Fit System offers easy adjustability for fit and positioning, plus enhanced ventilation and a durable design that resists abrasion, scratches and UV rays
    • Moto-style screw-in visor is easy to adjust with one hand, moving up and down in indexed steps with 3 riding positions plus a high position for goggle storage above your brow
    • An integrated rubber goggle gripper on the back of the helmet helps to ensure that your goggles stay in place, even when you're getting rowdy on the trail
    • Integrated eyewear grippers help secure sunglasses
    • Antimicrobial XT2 padding provides exceptional sweat absorption; pure silver content offers natural permanent odor protection to help keep your helmet feeling fresh


    To find your size, position a tape measure just above your ears and about 1 in. above your eyebrows. Keep the tape level to measure the circumference around the largest part of your head and then find the corresponding size in the Technical specs info.
