The Giro G10 MX Snowsports Helmet is a versatile all-terrain helmet with a removable visor, ready to meet your every demand on the mountain. Using a database of anatomic measurements, lab testing, and rider feedback Giro has refined this helmet to fit and perform at the highest level. The In-Mold construction fuses the outer shell with the impact-absorbing EPS liner for a lighter, more durable, better ventilated, and safety standard compliant (ASTM F2040 / CE EN 1077) helmet. The In Form™ 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 while the vertical tuning feature accommodates different goggles and head shapes for a custom fit, free of goggle gap. Thermostat™ Ventilation control 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. Super Cool™ vents pull cool, fresh air into the helmet while pushing heat and stale air out. By maximizing efficiency and optimizing vent shapes, the collective cooling power of Super Cool vents helps to regulate your core temperature and keep you feeling fresh all day. The Giro G10 MX is also compatible with all after market TuneUps systems.
