The Giro Nine Helmet is built to the nines. It boasts an in-mold construction, which combines a super sturdy polycarbonate shell with an impact-absorbing foam liner, offering excellent durability and protection. Its Super Cool™ vents kick out stale air, while pulling in fresh air, and Thermostat™ ventilation control gives you power over airflow through the use of a low profile button. Find your perfect fit using the glove-friendly In Form™ fit system, which utilizes a dial for easy adjustment and a gap-free fit. Perfect your gear setup with the Giro Nine Helmet.
In-Mold Construction In-Mold Construction fuses a tough polycarbonate outer shell with the helmet's impact-absorbing foam liner. The fusion process allows for better ventilation systems, making in-mold helmets lighter and cooler than traditional helmets.
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 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.
Stack Vent™ Stack Vent™ aligns the center top vent of the helmet with the center vent of your goggles to help eliminate fogging while maintaining total helmet and goggle integration.
In Form™ Fit System 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.
