Size Guide
HOW TO MEASURE YOUR SIZE
Wrap a measuring tape around your head, keeping the tape level from front to back. Note the measurement and reference the Size Guide.
| UNIVERSAL FIT WOMENS SIZE | CIRCUMFERENCE |
|---|---|
| UW | 50 - 57 cm |
Note: We recommend you try helmets on before buying. Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering your vision. Once you’ve got the right size, you can adjust the fit.
HOW TO ADJUST THE FIT
Step 1: Adjust the fit system at the rear of the helmet for a snug, secure fit. Some helmets also include a vertical tuning feature that allows you to adjust the fore/aft tilt, for optimal positioning on your head.
Step 2: Adjust the straps so that they sit just below the earlobes.
Step 3: Adjust the buckle so that it rests against the back of the jaw/throat.
Step 4: Adjust the interior pads if needed.
Step 5: Check the fit to make sure helmet is comfortable and secure. It should not roll forward or back, or be able to slide off.

Features
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 or 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 Mips 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.
