Integrated MIPS

Integrated Mips (Multi-Directional Impact Protection System) is designed to reduce rotational forces that can result from certain impacts. By integrating the Mips slip plane into the retention system, Bell is able to reduce complexity and weight for a compact, better ventilated helmet that fits more closely to the head.

Ergo Fit

A lightweight fit system with an easy-to-turn rubber overmolded dial for adjustments.

No-Twist Tri-Glides

Quick-adjust fasteners that help keep straps flat and properly positioned

Sweat Guide

Sweat Guide pad design pulls moisture away from the brow pad and away from eyewear.
