The Giro Decade Helmet is the much refined version of the original Giro Nine, done up with smooth, integrated styling and a super efficient 14-vent cooling system with Weatherstrip vent shields for ultra cold weather. Don't wait another ten years, it's time to upgrade your helmet now!
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.
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.
Super Cool™ Vents 14 Super Cool™ vents pull cool, fresh air into the helmet while pushing heat and stale air out.
Weatherstrip Vent Shields These seal off vents in extremely cold conditions, using a Hook-and-Loop Fastener tab to open or close the vent, but can't be misplaced like vent plugs.
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.
