Inspired by giant mountain landscapes and stylish smooth turns, the Neo(TM) helmet's distinct design lines provide a unique visual identity while encapsulating the two-polycarbonate components of the helmet. FEATURES: HARDSHELL WITH IN-MOLD HARDBODY(TM) LOWER WRAP - The two-piece shell combines a tough outer hard shell with a polycarbonate lower shell permanently fused to the liner for durability without excess weight. 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. STACK VENT TECHNOLOGY - Our Stack Vent was 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. THERMOSTAT CONTROL - 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.
