Giro Fixture Mips II Youth MTB Cycling Helmet







- All Giro helmets are designed to reduce as much energy as possible while meeting and 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.
- 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 Child and Youth Helmet Size Guide
How to measure your child's head size
To find the circumference of your child's head, place a tape measure in the centre of their forehead, wrap it around above their ears and around the back of their 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.
