Lightweight, impact‑responsive off‑road helmet with advanced ventilation and a low‑friction liner to reduce rotational forces.
The SM3 Heat Helmet is engineered for MX, Enduro and off-road use, combining innovations that prioritize ease of use, comfort and impact performance. 🔥
Its thermo-injected shell uses a special polymer blend with varying thicknesses to balance light weight and reliable impact protection.
A patented low-friction coating on the main EPS liner reduces rotational acceleration from oblique impacts by creating a slip plane that mimics the brain's natural cerebrospinal fluid.
The visor release system is designed to release at a predetermined force to help reduce neck loads during an impact.
Ten inlets and seven exhaust ports maximize ventilation and heat transfer to keep the rider cool during intense activity.
Engineered liners and multi-material construction work together to deliver consistent protection across demanding off-road conditions.
