The SM3 Heat helmet is engineered for aggressive off-highway and trail use, balancing comfort with impact performance. 🔥🏍️
Shell construction: a thermo-injected shell with a special polymer blend and variable thicknesses provides a lightweight design without compromising protection.
Low-friction coating on the inner EPS liner reduces rotational acceleration from oblique impacts by creating a controlled slip plane that mimics cerebrospinal fluid.
The patented visor release system disengages at a predetermined force to help reduce neck loads during an impact.
Ventilation is maximized with 10 inlets and 7 exhaust ports to promote efficient heat transfer and rider comfort.
