The Alpinestars SM3 Youth internal safety standard includes a more stringent chin impact test requirement than the certification standard, with the shell thickness and helmet structure optimized in the chin area. Weight: 1060 g (ECE) / 1170 g (DOT).
The Emergency Release System and removable cheek pads are integrated into the inner construction for controlled removal, while the 3D-molded foam provides a comfortable fit.
Stainless steel D-rings are used for the chin strap closure system.
The helmet is designed to comply with DOT certification and ECE 2206 approval for worldwide use.
