Alpinestars GP Plus V4 Sprint 1-Piece Leather Race Suit – Red / Fluo Red / Black

Engineered using extensive race feedback, the Alpinestars GP Plus V4 Sprint 1-Piece Leather Suit delivers track-grade performance, flexibility, and safety. Constructed from supple Flex Plus racing-grade bovine leather with dual-layered reinforcement in high-impact zones, this suit offers exceptional abrasion resistance while remaining lightweight. The bright red and fluo-red main body is accented with bold white Alpinestars branding, black inner-arm stretch sections, and deep black lower-leg panels for an aggressive track aesthetic.

Built for seamless integration with Alpinestars Tech-Air® airbag systems, the GP Plus V4 Sprint incorporates advanced Alpinestars Composite Stretch (A-CS®) panels across the back torso to provide superior elongation, tear resistance, and breathability. Perforated leather panels along the chest, abdomen, and thighs optimize cooling airflow during high-speed riding. Comprehensive impact protection is provided by Nucleon Race shoulder armor, GP-R elbow, knee, and shin guards, and external GP DFS sliders, all anchored within a pre-curved race fit featuring a Supertech R10 aerodynamic back hump.
