• MIPS® EVOLVE — Mips Evolve is designed to reduce rotational forces that can result from certain impacts. By integrating the Mips slip plane into the retention system, we are able to reduce complexity and weight for a compact, better ventilated helmet that fits more closely to the head.
• FLOAT FIT™ — A minimalist, lightweight fit system with an easy-to-turn rubber overmolded dial for adjustments (integrated with Mips®).
• ADJUSTABLE VISOR — Adjustable visor allows for sun protection and easy goggle storage.
• 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.
• GOGGLE GRIPPER — Rubber grip on the back of the helmet keeps your goggle strap in place.
