ALPINESTARS GP Plus v4 Sprint 1-Piece Leather Suit - Black/Red Fluo/White

Optimized to deliver race-grade technology, performance, protection and comfort, this one-piece leather suit is designed for track-focused riders and allows easy integration of the Tech-Air 7x Airbag System, while also accommodating the Tech-Air 7x sleeve display and the Tech-Air 10 wireless display.

Constructed from Flex Plus racing-grade leather with dual layers in exposed areas, the suit uses soft yet highly abrasion-resistant bovine leather that remains adaptive and flexible. Fully perforated leather panels and Composite Stretch (A-CS) technology on the back panel enhance airflow, breathability and freedom of movement while reducing weight and profile compared to traditional leather accordion panels (A-CS panels are about 9% lighter).

A-CS delivers around 30% elongation, boosting tear resistance by approximately 288% compared to HRSF and increasing cut resistance up to 600% versus leather. MATRYX on the shin optimizes resistance-to-weight ratio with high air permeability and engineered zoning where performance is needed most. Aramid reinforcements at elbow flexion zones add strength in critical areas.

Protection is race-focused: GP-R race-spec armor on elbows, knees and shins, Nucleon Race shoulder armor for superior impact protection, and race-proven GP DFS sliders with removable elbow sliders for controlled friction and abrasion management. The suit features a Race fit with highly pre-curved body, arms and knees for an aggressive riding position.

Incorporating a race-spec Supertech R10 aero hump engineered to work in conjunction with compatible helmets, the suit improves streamlining and aerodynamic performance when tucked into a racing crouch. Built to balance ventilation, mobility and maximum protection, this suit is engineered for riders who demand peak track performance and advanced safety system integration.
