This off-road helmet is engineered for MX, enduro and off-road use, with innovations optimized for comfort and impact performance. 🚵♂️
The thermo-injected shell uses a special polymer blend with varying thickness to balance impact protection and low weight.
An innovative low‑friction coating applied to the inner EPS liner reduces rotational acceleration from certain oblique impacts.
The slip‑plane layer mimics the brain's natural cerebrospinal fluid to help manage rotational forces during impacts.
A patented visor release system ensures the visor releases at a pre-determined force to help reduce neck loads in a crash.
Maximized ventilation features 10 inlets and 7 exhaust ports for efficient heat transfer and airflow. 🧠
