Flex Plus bovine ‘Race’ leather construction

Is 10% lighter than regular bovine leather, while delivering 80% more adaptability for superior freedom of movement, an ultra-adaptive race fit, and enhanced abrasion and tear resistance.

A-CS® Plus - Alpinestars composite stretch technology

Stretch panels on the torso for exceptional breathability, comfort, and freedom of movement, as well as delivering a lighter weight and a lower profile than a traditional leather accordion panel (the A-CS® Plus panels are about 9% lighter than leather panels).

Another key advantage of using A-CS® Plus is its superior stretch performance; A-CS® Plus has about 30% elongation, and offers an increase in tear resistance of 300% compared to HRSF (Hyper Resistant Stretch Fiber), and an increase in cut resistance by 600% versus leather.

Rideknit®

Combines high abrasion and tear resistance with high flexibility, comfort, and mechanical stretch while still delivering superior comfort and high levels of breathability.
