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 SPORT MIPS® FIT SYSTEM
The Roc Loc Sport Mips fit system offers easy one-handed operation with a 7cm adjustment range. Its confident clicking feel and sound lets riders know that the helmet is adjusting to a comfortable fit. With comfort similar to Roc Loc 5 and ponytail compatibility, the new Roc Loc Sport fit system brings premium function to sport level helmets.
UNIVERSAL FIT™ SIZING
Our Universal Fit helmets are sculpted to look good and fit great for almost anyone on the first try. By developing proprietary shell sizes based on specific customer groups, and combining them with an easily-adjustable fit system, it's easy for you get the right fit, straight out of the box, without the hassle or expense of trying multiple sizes.
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.
