Women's Series - is a collection of different helmet styles, fits and prices created for the needs of women. While the level of detail and color range is unique, these helmets do not have the unique "women's fit". This is because there are no anatomical differences between the heads of men and women, except for the average size of the diameter of the skull. And since the size of Giro helmets covers 98% of the human population, we believe that the Women's Series offers more options for women than any other brand.

Universal Fit Sizing - Our Universal Fit helmets are sculpted to look good the first time you try them on and are a great fit for everyone. By developing proprietary shell sizes based on specific customer groups and combining them with an easily adjustable fitting system, it's easy for you to get the correct size right out of the box without the hassle and expense of trying on multiple sizes.

The Roc Loc Sport Fit System offers easy one-handed operation with a 7cm adjustment range. The feeling and the sound of a click let rider know that the helmet is adjusting to a comfortable size. With a similar comfort system to Roc Loc 5 and a ponytail space, the new Roc Loc Sport fit system brings a premium feature to sports helmets.

The helmet does not have the MIPS system.
