Giro Fixture II Womens MTB Cycling Helmet







- In‐Mold Construction fuses a tough polycarbonate outer shell with the helmet's impact‐absorbing foam liner. The fusion process allows for better ventilation systems, making in‐mold helmets lighter and cooler than traditional helmets.
- The Roc Loc® Sport 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 Roc Loc 5 and ponytail compatibility, the new Roc Loc Sport fit system brings premium function to sport level helmets.
- Reflective Details enhance visibility at nighttime or in low‐light conditions when illuminated by a light source, such as headlights, by returning the light back to the source and reaching the driver's eye.
- 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.
Occasionally, without notice, manufacturers change product design and/or specifications.
Giro Women's Helmet Size Guide
How to measure your head size
To find the circumference of your head, place a tape measure in the centre of your forehead, wrap it around above your ears and around the back of your head. If there's a slight difference between two different sizes, always go for the tighter size.

Giro cycling helmets are adjustable so will fit a range of head sizes. Once you know the circumference of your head, select an appropriate helmet size. For example, if your measurement is 56cm then a size M (55-59cm) or a One Size (50-57cm) will fit you.
