Alpinestars S-M3 Solid

The Alpinestars S-M3 helmet is a high-performance off-road helmet engineered for motocross, enduro, and trail riders who demand maximum protection and comfort. Featuring an advanced thermo-injected polymer shell, the S-M3 offers optimal impact resistance while keeping the weight low, just 1430g.

This helmet shines in extreme conditions thanks to its 10 ventilation inlets and 7 exhaust ports that maintain airflow and regulate temperature during intense rides. For superior rotational impact protection, Alpinestars integrates its patented low-friction layer inside the EPS liner, designed to reduce rotational forces during oblique impacts.

The SM3’s innovative peak release system minimizes neck strain by releasing under precise pressure. Internally, the multi-density EPS system enhances energy absorption, while the removable cheek pads and emergency release system offer both convenience and safety.
