The Giro Radix MIPS Helmet is a rugged and reliable mountain bike helmet that gives you the air flow you need for unmatched comfort. Breathe easy with 25 vents which use Giro’s own Wind Tunnel Ventilation System to force cool air through the helmet and hot air out of the helmet. The Integrated MIPS® Technology is a highlight of this model, protecting you against rotational forces and offering excellent protection in combination with the full-wrap in mould polycarbonate shell with EPS liner. The ROC LOC Fit Adjustment System ensures that you can adjust the fit to suit your own personal needs and the visor P.O.V feature lets you adjust the visor to suit three riding positions. The Giro Radix MIPS Helmet gives you the ideal balance of safety, comfort and ventilation so that you can get the most out of your ride.

Features

MIPS: Integrated Mips® Technology: All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giro's MIPS-equipped helmets is to reduce rotational forces. 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.

Roc Loc 5.5 Mips®: 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.

Wind Tunnel Ventilation: Giro helmets are developed utilizing our proprietary Wind Tunnel ventilation system. This elaborate design combines active vents in the helmet's shell with exhaust channels inside the helmet that thrust fresh, cool air over and around the rider's head while forcing heat and stale air out. It's the most effective cooling system available, and a difference you can feel every time you ride.

P.O.V. Visor: Giro’s P.O.V. visor features an adjustment mechanism that lets you move the visor up and down in indexed steps. These steps include three riding positions plus a high position for goggle storage above your brow. The design allows you to easily adjust your visor with one hand while riding.
