  • Acu-Dial fit system can be adjusted with a single hand for a comfortable, secure fit
  • 22 vents provide airflow to keep you cool
  • Rear decal helps you stay visible on low-light rides


To find your size, position a tape measure just above your ears and about 1" above your eyebrows. Keep the tape level to measure the circumference around the largest part of your head and then find the corresponding size in the Specs below.

Rated 5 out of 5 by from I wold buy this again Fits as if made for me, a female. Visor is just rite for keeping sun from coming over my sun glasses but doesn't impede visual range. The straps come under my jaw just rite, so I don't ever tug on them to readjust during long rides. Really like this helmet

Rated 3 out of 5 by from Looks nice, cool color, too tight. I am not a big person but have a fairly large head. Even so, I measured it at 23" so this one should fit but it would actually hurt to wear it. Otherwise, it seems quite nice but it needs to be at least another inch or so larger to get a good fit.

Rated 5 out of 5 by from Comfortable and easily adjustable! I really liked what I got for the price. The helmet is easily adjustable and fits nicely. The bright yellow is easily seen by cars as an added benefit!

Rated 5 out of 5 by from Great value Really great, lightweight and low profile helmet. I didn't want anything too expensive, and this was a really great quality for price. I usually just bike to work and around town, so it's nice to have a helmet that is breathable so you don't get sweaty going into a store or office.

Rated 4 out of 5 by from A good, basic helmet I have to watch my budget and the padding in my old helmet was history... This one does the trick. It's reasonably comfortable at a very good price!

Rated 4 out of 5 by from Great Value This works great for me because I like to adjust size for use over a hat sometimes.

When they say size "U", means Universal Fit, from 50cm to 61cm ? Can woman use size "U" too ?

Asked by: Sharon
The "universal fit" is referring to a specific fit style from Giro. This helmet is unisex and can be worn by both men and women. We recommend comparing your measurements to head circumference listed in the specs to determine if this helmet will fit you.
