If relentless performance and style is what you're after, then you'll get it with the Giro Women's Seyen MIPS Road Bike Helmet.  The Giro Women's Seyen Mips is constructed with a slim design, luxurious fit, and highly-adjustable fit system will let you focus on what you do best, the ride.

• 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. 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.
• ROC LOC® 5 AIR FIT SYSTEM — In addition to helping to optimize stability and cooling airflow through the helmet; the micro-adjustable ergonomic and compact dial allows riders to adjust vertical positioning and tune the contact points independently for a customized fit with exceptional comfort.
• 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.
• IONIC+® PADDING — Pure Silver is the secret ingredient that gives IONIC+® the power to provide natural; permanent odor protection to keep your helmet feeling fresh.
