The skate-inspired MOD1 has been designed for those wanting a top-end freestyle helmet. Passive vents prevent your head from overheating during spring park sessions or hiking for lines. Brim/goggle ventilation allows hot air to flow away from your goggles for better anti-fog performance. The washable liner can be removed and goggles worn underneath. The magnetic Fidlock buckle is easy to do up while wearing gloves and the Boa sizing system allows for a comfortable and precise fit.Size GuideSmallMediumLargeX-Large51-55cm55-59cm59-61cm61-63cmClick here for more information on our Size & Fit GuideVenting: Passive Sizing System: Adjustable Weight: 400g Construction: In-Mould Safety standard: eN 1077 Class B, ASTM F 2040VentingPassive brim/goggle ventilation allows hot air to flow unobstructed from the goggle through the brim ventilation for better anti-fog performance.
