Product description
The safety of a full-face helmet combined with low weight, high comfort and excellent ventilation. The FULL-AIR MIPS is designed for situations where you conquer the climb under your own power.
With ASTM F1952-15 downhill certification, it's a full-face helmet that adopts many features and, above all, the feel of open-face helmets. It is well-ventilated and lightweight, making it comfortable and breathable even when climbing. The modular cheek pad system allows you to remove parts for better airflow or leave them in for a higher level of protection. The Fidlock magnetic buckle ensures easy and comfortable fastening under the chin.
The helmet features a smart quick-release action camera mount located under the visor, ideal for capturing POV riding footage.
The FULL-AIR MIPS is a lightweight yet very durable helmet for riders who pedal uphill themselves and go full throttle downhill.

MIPS - Multi-Directional Impact Protection System
MIPS is a slip liner between the EPS shell (helmet body) and the inner liners. In the event of an angled impact, the EPS shell of the helmet will roll a few millimetres over the MIPS layer, protecting the head and brain from the violent rotational jerk.
Although this movement is only on the order of a few millimeters, the result is that MIPS significantly reduces the amount of rotational force that might otherwise be transmitted to the brain.
