Giro Nine Snow Helmet Matte Black MD 55.5–59cm
Brand: Giro
Color: Matte Black

For more than a decade, The Nine has been a keystone staple in the Giro product line and is the product that started it all in performance snow helmets. The new Nine features an updated, streamlined low profile design, Thermostat Control and a full array of functional features that have made the Nine Giro's most enduring and popular design. Sizing:: Small: 52-55.5cmMedium: 55.5-59cmLarge: 59-62.5cmX-Large: 62.5-65cm. Stack Vent: Giro's Stack Vent was developed based on research showing the majority of the warm air that can cause fogging exhausts from the center top vent of the goggle. Aligning the Stack Vent in the helmet with the center vent of your goggles helps to keep them clear and fog free while maintaining total helmet and goggle integration.. In-Mold Construction: In-mold construction fuses a tough polycarbonate outer shell with the helmet's impact-absorbing foam liner. The fusion process allows us to sculpt better ventilation systems, so In-mold helmets can be lighter and cooler than traditional helmets.. Thermostat Control: 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.
