Flex Plus ‘racing-grade’ leather features dual layers in exposed areas for enhanced durability. Soft and supple, this premium bovine leather delivers outstanding abrasion resistance while remaining highly flexible and adaptive.
Alpinestars Composite Stretch (A-CS®) technology on the back panel ensures exceptional breathability, comfort, and freedom of movement. A-CS® Tech is not only lighter and more compact than traditional leather accordion panels—approximately 9% lighter—but also provides superior stretch performance with 30% elongation. Additionally, it offers a remarkable 288% increase in tear resistance compared to HRSF (Hyper Resistant Stretch Fiber) and a 600% improvement in cut resistance over leather.
Fully perforated leather panels further enhance airflow and breathability, ensuring optimal cooling performance.
