Helmet ALPINESTARS SM3 Heat

• 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.
• Shell construction featuring a thermo-injected shell incorporating a special polymer blend enhanced by varying degrees of thickness, engineered to deliver an optimal combination of impact protection and light weight.
• Alpinestars patented innovative low-friction coating is applied to the inner part of the main EPS liner to reduce rotational acceleration forces that can result from certain oblique impacts.
• This layer acts as a slip plane to mimic the brain's own low-friction cerebrospinal fluid, which is the body's natural defense against oblique impacts.
• Patented visor release system ensures visor release with the correct predetermined force, effectively reducing forces on the neck during an impact.
• Maximized ventilation and high levels of heat transfer exchange thanks to 10 inlets and 7 exhaust ports.
