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, we are able to reduce complexity and weight for a compact, better-ventilated helmet that fits more closely to the head.

Ergo Fit & No-Twist Tri-Glides Sleek, easy-to-use dial system for one-handed adjustments (integrated with MIPS layer). Quick-adjust fasteners that help keep straps flat and properly positioned.

Sweat Guide & Goggle Gripper Sweat Guide pad design pulls moisture away from the brow pad and away from eyewear. Rubber grip on the back of the helmet keeps your goggle strap in place.

Size Specifications Small/Medium (50-57 cm), Medium/Large (53-60 cm), and X-Large (56-63 cm) Sizes. Important always take a head measurement. Head sizes and shapes can vary, even within an age range. Using a helmet that does not fit can be dangerous.
