Alpinestars GP Plus v4 Sprint 1-Piece Leather Suit

The Alpinestars GP Plus v4 Sprint 1-Piece Leather Suit is engineered for professional racers and track enthusiasts seeking the ultimate balance of performance, protection, and comfort. Crafted from Flex Plus ‘racing grade’ bovine leather with dual-layer construction in exposed areas, this suit provides superior abrasion resistance while maintaining a soft, supple feel for unrestricted movement. The race-fit design is highly pre-curved at the body, arms, and knees to minimize fatigue and maximize aerodynamic efficiency when tucked in a racing crouch.

At the core of its innovation is the Composite Stretch (A-CS) technology on the back panel. This advanced material is approximately 9% lighter than traditional leather panels and offers 30% elongation, providing a significant 288% increase in tear resistance and a 600% increase in cut resistance compared to standard leather. For optimal thermal regulation, fully perforated leather panels are strategically placed to enhance airflow and breathability during high-intensity sessions.

Safety is paramount, with the suit featuring race-spec GP-R armor on the elbows, knees, and shins for extended impact coverage. Impact protection is further reinforced by Nucleon Race shoulder armor and race-proven GP DFS sliders with removable elbow sliders for effective friction management. The shins utilize MATRYX® material to deliver a high resistance-to-weight ratio and flexibility, while aramid reinforcements at key flex zones add critical strength where it is needed most.

Designed for the future of rider safety, this suit is fully optimized for seamless integration with the Tech-Air® 7x and Tech-Air® 10 Airbag Systems, including compatibility for sleeve and wireless displays. To complete the performance package, the integrated Supertech R10 aero hump is engineered to work in harmony with Alpinestars helmets, streamlining airflow and reducing drag at high speeds.
