Giro Radix with MIPS Trail Bike Helmet

Giro Radix with MIPS Trail Bike Helmet 

Built for the rugged adventurer who appreciates a perfect fit, the Giro Radix MIPS bike helmet keeps the sun out of your eyes and delivers plenty of ventilation.

• Lightweight, stable and comfortable, the highly adjustable Roc Loc 5.5 MIPS Fit System allows you to quickly and easily tune fit tension and fore/aft tilt using a single hand
• Rotational motion can cause brain injuries; with MIPS, a low-friction layer slides 10 to 15mm in all directions, reducing rotational motion to the brain during impact
• P.O.V. visor offers 15° of adjustment to help keep the sun out of your eyes without obstructing your vision
• In-mold construction fuses a tough polycarbonate outer shell with an impact-absorbing foam liner; fusion process allows for lighter helmets and better ventilation
• Wind Tunnel ventilation system combines active vents in the shell with internal exhaust channels that thrust fresh, cool air over and around your head and forcing hot air out
