The Radix MIPS helmet combines rugged style and durability to meet the demands of core trail riders, with the coverage, lightweight, and ventilation riders need to ride comfortably and confidently, all day.

The Radix MIPS helmet is for the rugged adventurer who appreciates a perfect fit, the sun staying out of their eyes, and plenty of ventilation.
