TECHNOLOGIES:

• Women's Series - is a collection of different helmet styles, fits and prices created for women's needs. While the level of detail and color range is unique, these helmets are not uniquely "women's specific." This is because there are no anatomical differences between the heads of men and women, except for the average size of the skull diameter. And since Giro helmet sizes cover 98% of the human population, we believe 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 on the first try on and fit perfectly for everyone. By developing proprietary shell sizes based on specific customer groups and combining them with an easy-to-adjust fit system, it's easy for you to get the right size, straight out of the box, without the hassle and expense of trying on multiple sizes.

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

The helmet does not have the MIPS system.
