A super-lightweight modern women's trail helmet - that's the Radix W. The shape of the helmet is literally chewed to the bone - no design frills and no viewer frills. Simplicity is power! The comfort and level of protection will give you confidence even on day-long expeditions into technical terrain. A perfect fit on your head is ensured by the Roc Loc 5.5 clamping system, which you can adjust to your exact needs. MIPS technology available in selected colours. MIPS (Multi-Directional Impact Protection System) provides increased protection against rotational forces on the head. The new MIPS technology aims to eliminate the rotational forces that act on the head in the event of a crash. When hit at any angle, the MIPS system allows the EPS shell of the helmet to rotate independently around the rider's head. WHAT IS MIPS (Multidirectional Impact Protection System) and how does it work? MIPS is a slippery liner between the EPS shell (helmet body) and the inner liners. In the event of an angled impact (for example, if you catch your head on a branch), the EPS shell of the helmet will roll a few millimeters over the MIPS layer, protecting your head and brain from a violent rotational jerk.
