Giro Radix Helmet

MIPS, or Multi-directional Impact Protection System, is designed to reduce rotational forces on the brain during certain types of impacts. It acts as an internal slip-plane that allows the helmet to slide slightly relative to your head during a crash, providing an extra layer of safety beyond standard impact absorption.

The Roc Loc 5 is a dial-based system that allows you to adjust both the fit tension and the vertical position of the helmet with one hand. It ensures the helmet sits securely on your head without feeling tight or creating pressure points, which is essential for stability on rough trails.

Yes, the P.O.V. visor is adjustable, allowing you to move it up or down with one hand while riding. This is helpful for blocking sun or rain, or for clearing your field of vision when you need to look further ahead on technical descents.

The Radix features 25 vents designed with Giro's Wind Tunnel ventilation system, which creates internal channels to pull cool air over your scalp while pushing hot, stale air out. It is highly effective at keeping you comfortable during long, sweaty climbs.

The women-specific design accounts for differences in head shape and volume, typically offering a slightly different internal profile to ensure a more secure, comfortable fit for women. It is engineered to prevent the helmet from shifting or feeling loose, which is a common issue with unisex sizing.

Yes, at 316 grams, it is lightweight enough for all-day comfort without sacrificing the durability needed for technical singletrack. The combination of the adjustable fit system and high-flow ventilation makes it a solid choice for extended rides.
