A proven favorite for more than a decade. This lightweight helmet is defined by its low profile and streamlined silhouette. A wealth of features – including the custom tuning of the In Form Fit System and Thermostat Control venting – make the Nine one of Giro’s most enduring and popular performance snow helmets.
IN FORM™ FIT SYSTEM: The In Form™ system is a low-profile fit and stability system that makes it easy to dial-in the fit and feel of your helmet in seconds – even with gloves on. An ergo-friendly dial at the base of the helmet provides up to 6 cm of fit adjustment, and the system also includes a separate vertical turning feature that adjusts the fore / aft tilt of the helmet on your head to enhance peripheral vision and optimize the fit of the helmet with goggles.
SUPER COOL™ VENTS: 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.
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.
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.
