• 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.

• HRSF (Hyper Resistant Stretch Fabric) for high abrasion and tear resistance, and exceptional freedom of movement.
• MATRYX® on the shin is engineered to offer maximum resistance-to-weight ratio together with high air permeability and flexibility, with engineered zoning to boost the performance where needed.
• Aramid reinforcements at the elbow flexion zones for additional strength in a key area.
