Designed for the dedicated trail rider, the Giro Radix MIPS Helmet marries lightweight, ventilated design with robust durability for all-day comfort and confidence. The helmet's durable in-mould construction bonds a tough polycarbonate shell with an EPS liner, optimizing protection without unnecessary weight, while the adjustable P.O.V.™ visor enhances visibility and adaptability. Featuring the adjustable Roc Loc 5 MIPS system, the Radix offers superior fit customization and additional protection against rotational forces from angled impacts.

MIPS is a system used to reduce the rotational forces on the brain in the case of oblique impacts. This is achieved by allowing a controlled rotation of the shell relative to the liner.


This groundbreaking fit system provides unmatched comfort. Roc Loc 5 is nearly 40-percent lighter than its popular predecessor, Roc Loc 4. With Roc Loc 5, you can easily dial-in both fit tension and adjust vertical position with a single hand. Just twist the Micro Dial for a tighter feel on rough terrain, then back it off a notch and relax across the flats or a warm climb.
