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

Designed for aggressive trail and competition riding, this helmet balances comfort with proven impact performance. 🪖

The thermo-injected shell uses a graduated polymer layup that varies thickness to optimize protection while keeping weight low.

A patented low-friction coating is applied to the interior EPS liner to reduce rotational acceleration during oblique impacts, mimicking the brain's natural cerebrospinal fluid slip plane. 💨

The visor features a patented release mechanism that disengages at a predetermined force to help reduce neck loads in an impact.

Maximized airflow is achieved through multiple intake and exhaust ports for effective heat transfer and comfort during long rides.
