Redesigned with a low-friction slip-plane interior, the Bell Stoker MIPS Equipped MTB Helmet reduces the energy transferred to the head from rotational impacts, creating a new threshold for rider protection. It's also built to tame every trail and loaded with performance enhancing features for all-mountain epics and singletrack ventures. Fusion In-Mold Polycarbonate Shell with extended rear coverage puts more protection at the back of the head. 13 channeled openings with Velocity Flow Overbrow ports increase airflow, so your cranium and forehead stay cool and sweat-free. Variable Position Visor protects your eyes from sun, rain and trail debris, plus it can move up to 15 with a simple tug up or down. SpeedDial retention system combines unmatched comfort with a glove-like fit.
