ALPINESTARS(MX) SM3 Solid Helmet — Size L, Black Matte

This off-highway head protector is engineered for aggressive terrain riding, featuring innovations optimized for ease of use, comfort and impact performance. 🪖

• Thermo-injected shell construction uses a special polymer blend with varying wall thicknesses to balance impact protection and lightweight behavior.
• A patented low-friction coating is applied to the inner EPS liner to reduce rotational acceleration from oblique impacts.
• The added slip-plane layer mimics cerebrospinal fluid to help manage rotational forces during angled impacts.
• A patented visor release system disengages at a predetermined force to help reduce neck loads in the event of an impact.
• Maximized airflow through 10 inlets and 7 exhaust ports provides efficient heat transfer and cooling.
• Composition: 48% acrylonitrile-butadiene-styrene, 20% polyurethane, 16% polystyrene (EPS), 6% polypropylene, 4% polyvinyl chloride, 2% ethylene-vinyl acetate, 2% steel, 1% expanded polypropylene, 1% polyamide.
