Additional Details and Features Integrated Mips® Brain Protection System - All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giro's Integrated Mips®-equipped helmets is to reduce rotational forces while enhancing fit and comfort by combining the Mips slip plane with the Helmet's adjustable fit system. Giro believes that helmets equipped with this technology can reduce the amount of rotational force that may be transferred to rider's brain in certain impacts. Hardshell with in-mold Hardbody™ Lower Wrap - The two-piece shell sombines 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. 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. Vertical Tuning - Accommodates different goggles and head shapes for a custom fit free of gaper gap. In Form Fit System - The 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.
