The Decade sets the bar a notch higher for women who are looking for style, performance, and value. It has all the features of our Nine.10 and adds considered finishing throughout specifically for women.
Although there is no difference between male and female head shapes other than a smaller average size, we offer women's specific models to keep up with the fashion forward kit found on the mountain. Finishing details and a sophisticated color palette set these models apart.

Sizing

The In form fit system gives easy, quick and effective adjustment to ensure the best fit possible
The In Form system makes it easy to dial in a custom fit in seconds - even with gloves on. An ergo-friendly dial at the base of the helmet provides up to 6cm of adjustment and enhanced stability while the vertical tuning feature accommodates different goggles and head shapes for a custom fit, free of gaper gap.
In-mould construction fuses a tough polycarbonate outer shell with the helmet's impact-absorbing foam liner for extra durability without excess weight
In-mould 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-mould helmets can be lighter and cooler than traditional helmets.
The new Weatherstrip vent shield allows you to control the airflow into the helmet to keep your head at an optimum temperature without the need for removing vent plugs
Weatherstrip Vent Shield work to seal off vents in extremely cold conditions. A Velcro tab secures the shield when not in use to allow proper ventilation. Simply open the Velcro tab to unroll the shield over its corresponding vent. The inclusion of the Stack Vent system allows for the perfect integration with goggles by allowing warm air from the goggle vents to exit freely and not be trapped in by the helmet brim
Compatible with Skullcandy TuneUps
Super Fit Engineering is the foundation of our product design process. Every new Giro product is designed with reference to our database of anatomic measurements and rider input. We then test the design repeatedly in the lab and in the hands of riders so we can gather feed back and make refinements to create a final product that fits and performs at the highest level.
