FEATURES

• INTEGRATED MIPS® PROTECTION: Reduces rotation forces while enhancing fit and comfort by combining the MIPS slip plane with the helmet's adjustable fit system.
• HARDSHELL CONSTRUCTION: Produces great helmets at a great price. A rugged outer shell is molded and then attached to the EPS foam liner.
• SEAMLESS COMPATIBILITY: For optimal performance of both helmets and goggles, Giro products are designed to work together, ensuring a seamless interface between helmet and goggle for an exceptional fit and dependable, worry-free function.
• THERMOSTAT CONTROL: Adjustable venting allows you to custom-tune airflow instantly with a simple, low profile control button on the outside of the helmet. No other system is faster or easier to adjust, and nothing is more effective at keeping you comfortable.
• STACK VENT TECHNOLOGY: Developed based on research showing the majority of warm air that can cause fogging comes from the goggle's center top vent. Aligning the Stack Vent in the helmet with the center vent of the goggle helps keep it clear and fog-free.
• VERTICAL TUNING: Accommodates different goggles and head shapes for a custom fit free of gaper gap.
• 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.
