The SM3 Helmet is engineered for MX, enduro and off-road use, featuring innovations and technologies optimized for ease of use, comfort and impact performance. 🚵♂️
The shell construction uses a thermo-injected process with a special polymer blend and varying thicknesses to deliver the optimal balance of impact protection and low weight.
An Alpinestars-patented low friction coating on the inner EPS liner reduces rotational acceleration from certain oblique impacts by acting as a slip plane similar to the brain's cerebrospinal fluid.
The patented visor release system ensures the visor releases at a predetermined force to help reduce forces on the neck during impact, while maximized ventilation is achieved through 10 inlets and 7 exhaust ports for efficient heat transfer. 🔄
