The Crue MIPS has skate styling and maximum safety for park rats and all-mountain shredders. Hard shell construction ensures it\'s tough, carefully positioned vents help with cooling and Giro\'s In Form fit system allows for plenty of adjustment. Best of all though, MIPS increases safety by reducing the rotational forces on the brain that can occur during oblique strikes.Size GuideX-SmallSmallMedium48.5-52cm52-55.5cm55.5-59cmVenting: PassiveSizing System: AdjustableWeight: 475gConstruction: Hard ShellSafety standard: EN 1077 Class B Additional SafetyMIPS can provide more protection in certain impacts. The main components of a MIPS equipped helmet are 1. The Interior Foam Liner, 2. the Low Friction Liner and 3. an elastomeric attachment system. In an angled impact, the elastomeric attachment system stretches to allow the foam liner to rotate independently around your head.VentingStack Venting was developed based on research showing the majority of the warm air that can cause fogging exhausts from the centre top vent of the goggle. Aligning the Stack Vent in the helmet with the vent of your goggles helps to keep them clear and fog-free.The Super Cool passive vents are non-adjustable but allow air to flow easily.Sizing SystemThe In Form fit system makes it easy to dial in a custom fit in seconds, even with gloves on. An ergo-friendly dial at the base of the helmet provides up to 6cm of adjustment and enhanced stability. The Vertical Tuning feature accommodates different goggles and head shapes for a custom fit free of gaper gap.ConstructionHard shell construction produces tough helmets that are great value. A rugged outer shell is moulded and then attached to the EPS energy absorbing foam liner.
