Alpinestars SM-5 Course Blue

The Alpinestars SM-5 Course Blue utilizes a multi-density EPS liner system designed to optimize energy absorption across varying impact vectors. The outer shell is constructed from high-grade carbon fiber composite, offering an exceptional strength-to-weight ratio that reduces rotational forces during lateral impacts while maintaining structural rigidity. Integrated with the MIPS (Multi-directional Impact Protection System) technology, the helmet features a low-friction slip plane that allows the inner liner to rotate independently of the head upon oblique impacts, significantly reducing the risk of traumatic brain injury.
