The Alpinestars S-M10 Deegan helmet features a high-density 3K carbon fiber outer shell reinforced with a uni-directional carbon composite layer to optimize strength and energy dissipation. Inside, a multi-density EPS liner is engineered with targeted densities across specific crash impact zones, while a Multi-Directional Impact Protection System (MIPS) layer is integrated to reduce rotational motion imparted to the brain during angled impacts. The shell’s base profile includes a sculpted Collarbone Protection design utilizing energy-absorbing EPP (Expanded Polypropylene) foam to minimize clavicle injury risks.
Fit and safety mechanisms are managed through Alpinestars’ patented A-Head interior fitment adjustment system, which allows for micro-tuning of crown height and forward riding angle within the shell. Additionally, the helmet incorporates a patented Visor Release System designed to detach cleanly upon impact regardless of the impact angle, a feature engineered to prevent the transmission of rotational force.
