The Sonnet™ is a favorite in our Women’s Series collection, offering acclaimed fit and performance for riders who enjoy great routes as much as a swift pace. The slim shape offers great ventilation thanks to 25 Wind Tunnel™ vents and the comfortable convenience of the adjustable Roc Loc® 5 fit system. And with the light weight and durability of In-Mold construction, it won’t weigh you down. Sonnet MIPS models are available with the Multi-Directional Impact Protection System. We believe MIPS can redirect energy and provide more protection in certain impacts.

All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giro’s MIPS-equipped helmets is to reduce rotational forces. Giro believes that helmets equipped with this technology can reduce the amount of rotational force that may be transferred to rider’s brain in certain impacts.

Sonnet: Women's Series Design
The Sonnet is a great addition to our Women's 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.
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.
