Sonnet: Womens Series Design:
The Sonnet is a great addition to our Womens Series collection, offering an amazing fit for riders who enjoy great routes as much as a swift pace. The slim shape combines impressive ventilation thanks to 25 Wind Tunnel vents.

The Women’s Series is a diverse collection of helmet styles, fits and prices tailored to the demands of female riders. While the level of detail and range of colors is unique within the Women’s Series helmets, they do not feature a unique “women’s fit.” That’s because there is no anatomic difference between women and men’s heads except for the average skull diameter measurement. And since Giro helmet sizes cover 98% of the human population, we believe the Women’s Series offers more options to women than any other brand.

Giro helmets are developed utilizing our proprietary Wind Tunnel ventilation system. This elaborate design combines active vents in the helmet’s shell with exhaust channels inside the helmet that thrust fresh, cool air over and around the rider’s head while forcing heat and stale air out. It’s the most effective cooling system available, and a difference you can feel every time you ride.

Our proprietary Super Fit sizing system is based on “human scale factors” data and over 25 years of handcrafting helmets. By creating helmet molds in up to 4 adult sizes to match the human body’s form, our Super Fit sizes comfortably and securely fit riders, and feel like they are custom made just for you.

ROC LOC 5 Fit System:
The industry benchmark in comfort, stability, adjustability and weight savings. In addition to enhancing the fit and comfort of helmets, Roc Loc 5 allows you to easily custom tune the fit tension and the fore-aft tilt of the helmet in seconds using a single hand. And it’s lighter than comparable systems too, making it the ultimate in skull-hugging luxury.

In-Mold Construction fuses a tough polycarbonate outer shell with the helmets impact-absorbing foam liner. The fusion process allows for better ventilation systems, making in-mold helmets lighter and cooler than traditional helmets.
