The GIRO Radix MIPS Helmet is a rugged mountain bike helmet that will suit the seriously adventurous dude who loves the dirt! It is a combination of tough style and strong durability for the serious mountain bikers who are dedicated to the technical single-track. It is a really lightweight helmet that is well ventilated to keep the head cool and comfortable even on a long, hot day in the saddle. The adjustable Roc Loc 5 and MIPS fitting system will keep your head really safe with a good, secure fit, also giving that extra comfort and protection from rotational forces in the unfortunate event of a stack. The tough P.O.V. visor can be adjusted for up to 15 degrees. The shell of the helmet is made from polycarbonate and is fused to the EPS foam liner, which enhances durability and ventilation without adding extra weight and bulk.
