Giro Radix MIPS Bike Helmet

Polycarbonate Shell with EPS Liner

In-Mold Construction – In-mold construction fuses a tough polycarbonate outer shell with the helmet’s impact-absorbing foam liner. The fusion process allows Giro to sculpt better ventilation systems, so In-mold helmets can be lighter and cooler than traditional helmets.

Roc Loc® 5.5 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. It's lighter than comparable systems too, making it the ultimate in skull hugging luxury.

Wind Tunnel™ Ventilation – Giro helmets are developed utilizing the proprietary Wind Tunnel™ ventilation system, which combines active vents with internal exhaust channels that thrust cool, fresh air over and around the riders head-while forcing heat and stale air out. This significant increase in air channeling makes a difference that riders will immediately feel and appreciate.

25 Vents

MIPS® Equipped – MIPS technology is designed to reduce rotational force to the brain in certain types of glancing or angled blows - this is accomplished by allowing the inner frame of the helmet to move slightly relative to the outer shell.

POV Visor – Giro's P.O.V. Visor features an adjustment mechanism that lets you move the visor up and down through 15° in indexed steps, including three riding positions plus a high position for goggle storage. This design allows you to easily adjust your visor with one hand while riding.

Complies with the US CPSC Safety Standard for Bicycle Helmet for Persons Age 5 and Older
