Technologies:

Roc Loc® 5 Fit System:
- The industry benchmark in comfort, stability, adjustability and weight savings. In addition to enhancing the fit and comfort of helmets, Roc Loc® 5 allows you to easily custom tune the fit tension and the fore-aft tilt of the helmet in seconds using a single hand. And it´s lighter than comparable systems too, making it the ultimate in skull-hugging luxury.

Tool-free, Bolt-on Visor:
- Easily adjustable without need for tools or extra fiddling, and offers plenty of vertical adjustment to stage goggles when you´re not wearing them.

In-mold Lower Hardbody™ Wrap:
- The In-Mold process permanently fuses a light-yet-tough polycarbonate shell to the foam liner, eliminating adhesives and excess weight. Our Hardbody design extends that coverage to the inside of the helmet to enhance durability.

Integrated Mips® Brain Protection System:
- 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.

Wind Tunnel Internal Channeling:
- Combined with the massive vents, internal channeling forces air to flow over the scalp, providing remarkable cooling power.

Roc Loc® 5 Fit System:
- The industry benchmark in comfort, stability, adjustability and weight savings. In addition to enhancing the fit and comfort of helmets, Roc Loc® 5 allows you to easily custom tune the fit tension and the fore-aft tilt of the helmet in seconds using a single hand. And it´s lighter than comparable systems too, making it the ultimate in skull-hugging luxury.

EN1078 IMPORTANT NOTE This helmet has been built, tested and approved according to the European regulations ECE/ONU R22.05. TRADEINN is not responsible for the use that may be made of this helmet in other countries that are not subject to this European homologation ECE/ONU R22.05, discouraging the use of this in those countries.

This helmet stands out for its comfort, is well-ventilated, and you can´t tell you´re wearing it once you adjust it. The weight is very low, which is appreciated. The MIPS system is a plus in case of an accident

I have used Giro MTB and snow boarding helmets for nearly15yr and have never been disappointed in their products. I have a large head and the Large (L) is true to size. The Roc Loc 5 system works a treat. Looking forward to using it on the trails
