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 - Fuses a tough polycarbonate shell with an impact-absorbing foam liner, allowing for lighter weight helmets with superior venting.
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 - An ergo-friendly dial at the base of the helmet provides up to 6 cm of adjustment and can be easily adjusted with gloves on. The vertical tuning feature accommodates different goggles and head shapes for a gap-free fit.
