🔥 The SM3 Heat Helmet is engineered for MX, enduro and off‑road use, combining ease of use, comfort and impact performance.
The thermo-injected shell uses a special polymer blend with varying thicknesses to balance impact protection and light weight.
A patented low-friction coating on the inner EPS liner reduces rotational acceleration from oblique impacts by acting as a slip plane similar to the brain's natural cerebrospinal fluid.
The visor release system is patented to release at a predetermined force, helping reduce forces on the neck during an impact.
Maximized ventilation and high heat exchange are achieved through 10 inlets and 7 exhaust ports. Construction includes: 48% acrylonitrile-butadiene-styren, 20% polyurethane, 16% polystyrene (EPS), 6% polypropylene, 4% polyvinyl chloride, 2% ethylene-vinyl acetate, 2% steel, 1% expanded polypropylene, 1% polyamide.
