Suitable forWomen

Giro was founded in 1985 by Jim Gentes, with obsession for design and answering unmet needs. That obsession led him to start making his own products and ultimately resulted in a company committed to serving the rider through personal expression and advanced performance.

The Seyen Mips® combines a touch of european flair with slightly deeper coverage and high-performance features—all tucked into a very slim design.

The outer shell is molded from a tough polycarbonate that's fused permanently to the EPS foam liner using our In-Mold construction process to enhance durability and ventilation without excess bulk. The fit is luxurious and secure, thanks to our highly-adjustable Roc Loc 5 Air Mips® system that allows you to customize fit/feel for great stability and long-range comfort. Another benefit is integrated Mips® which can provide an added measure of protection from rotational forces in the event of an angled impact.


Hardshell With In-Mold hardbody™ Lower Wrap

The two-piece shell combines a tough outer hard shell with a polycarbonate lower shell permanently fused to the liner for durability without excess weight.

Integrated MIPS® Brain Protection System

All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giro's Integrated Mips®-equipped helmets is to reduce rotational forces while enhancing fit and comfort by combining the Mips slip plane with the helmet's adjustable fit system. 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. Learn more about Mips in the video above.

Roc Loc® 5 Air Fit System

This revolutionary fit system adds a new dimension to helmet performance by enhancing cooling, as well as fit comfort and stability. Using a patented design that suspends the helmet just slightly off the top of the skull, Roc Loc® 5 Air allows cool airflow to pass directly over your head, further enhancing the performance of vents and internal channeling that exhaust heat out of the helmet. Fit and feel adjustments mimic the Roc Loc 5, allowing you to easily custom tune fit tension and fore-aft tilt of the helmet in seconds using a single hand.

Wind Tunnel Ventilation

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.

Women's Series

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 Womens 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.
