The Radix MIPS helmet combines rugged style and durability to meet the demands of core trail riders, with the coverage, light weight, and ventilation riders need to ride comfortably and confidently all day.. The highly adjustable Roc Loc 5.5 MIPS system allows you to customize fit and feel for enhanced stability and long-range comfort while providing an added measure of protection from rotational forces in the event of an angled impact. The P.O.V. visor offers 15 degrees of adjustment, and the tough polycarbonate outer shell is fused permanently to the EPS foam liner using Giro's In-Mold construction process, to enhance durability and ventilation without excess bulk.
