The SM3 Force Helmet is engineered for aggressive off-road disciplines, combining innovations that prioritize ease of use, comfort and impact performance. 🏁

• Thermo-injected shell using a special polymer blend to balance impact protection with light weight.
• A patented low-friction layer inside the main EPS liner reduces rotational acceleration from oblique impacts.
• This slip-plane layer mimics the brain’s cerebrospinal fluid to help manage oblique forces.
• Patented visor release system ensures the visor releases at a predetermined force to reduce neck loads during an impact.
• Maximized ventilation with 10 inlets and 7 exhaust ports for efficient heat transfer and airflow.

Designed for long rides, the helmet balances protection, comfort and airflow for demanding terrain. 🏍️
