Full of features for comfort and safety it\'s no wonder the Pioneer MIPS is a best-seller. Salomon’s EPS 4D construction offers increased shock absorption over the industry standard and MIPS reduces the effects of rotational forces from an oblique blow. The Custom Dial size system ensures a good fit and active ventilation allows the user to fine-tune the airflow.Size GuideSmallMediumLargeX-Large53-56cm56-59cm59-62cm62-64cmClick here for more information on our Size & Fit GuideVenting: ActiveSizing System: AdjustableWeight: 380gConstruction: In-MouldSafety standard: EN 1077 Class B, ASTM F 2040 Additional SafetyThe MIPS Brain Protection System is a helmet-integrated, low-friction layer designed to reduce rotational motion transferred to the brain from angled impacts to the head.Salomon\'s patented EPS 4D technology works like a crumple zone, maximising energy absorption and protecting from oblique and vertical shocks.VentingActive Ventilation allows the airflow to be fine-tuned easily by sliding the vent covers open or closed using the button on the outside.Salomon’s Airflow Concept uses built-in channels within the EPS 4D liner which allows an even temperature and constant airflow between your head, your helmet and your goggles.Sizing SystemThe Custom Dial fit system provides a quick, easy and effective adjustment for a precise and comfortable fit. Helmet shape is based on Salomon\'s round fit.ConstructionIn-mould construction uses a lightweight polycarbonate shell fused with an EPS energy absorbing liner for maximum protection and comfort.
