Alpinestars GP Plus v4 Sprint 1-Piece Leather Suit - Black/Red Fluo/White, US 38 / EU 48 (Part No. 3150225-1231-48)

The Alpinestars GP Plus v4 Sprint 1-Piece Leather Suit is engineered for racing enthusiasts seeking maximum performance, protection, and comfort. Crafted from race-grade Flex Plus bovine leather, this suit features dual-layer panels in exposed areas for enhanced abrasion resistance. The soft, supple leather adapts to body movements, ensuring a snug fit without sacrificing flexibility. Additionally, the suit incorporates advanced composite stretch (A-CS) technology on the back panel, providing exceptional breathability, increased mobility, and a lighter profile—approximately 9% lighter than traditional leather panels. The suit’s design emphasizes durability and resilience with 30% elongation and a remarkable 288% increase in tear resistance over hyper-resistant stretch fibers, along with a 600% boost in cut resistance compared to standard leather.

Designed for high-performance racing, this suit includes fully perforated leather panels that promote airflow and keep the rider cool during intense sessions. Safety is prioritized with race-spec GP-R armor on the elbows, knees, and shins, offering extended coverage in critical zones. Removable GP DFS sliders on the elbows facilitate effective friction control during falls, while Nucleon Race shoulder armor ensures superior impact absorption and abrasion resistance. The inclusion of MATRYX® material on the shins delivers an optimal balance of resistance-to-weight ratio, flexibility, and high air permeability, with engineered zoning to reinforce areas where strength is most needed.

Additional features include aramid reinforcements at key flexion zones for added durability, a race fit with a highly pre-curved body, arms, and knees for enhanced riding performance, and an integrated Alpinestars Supertech R10 aero hump. This aerodynamic feature is specifically designed to work seamlessly with the Supertech R10 helmet, optimizing streamlining and reducing turbulence when tucked into a racing crouch. The suit's comprehensive protection, innovative materials, and ergonomic design make it an ideal choice for professional racers and serious track day riders seeking the ultimate in motorcycle racing gear.
