The Alpinestars GP Plus v4 Tech-Air Ready Leather Suit delivers advanced race-inspired protection, mobility, and comfort for sport and track riders. Finished in Black, Red Fluo, and White, this upper mid-level one-piece suit is designed in a US 46 / EU 56 size and features an updated construction compared with the GP Plus v3 model. The suit combines Flex Plus racing bovine leather, Alpinestars Composite Stretch Plus material, Matryx panels, HRSF stretch inserts, and GP Dynamic Friction Shield sliders for a precise, performance-focused fit.
The Flex Plus race leather is specially tanned and refined in Italy to provide improved flexibility, feel, and adaptability while maintaining professional racing standards for abrasion and tear resistance. A-CS Plus stretch material on the side torso and shoulder blades contributes to enhanced elongation, reduced weight, breathability, and freedom of movement compared with traditional leather accordion panels. Perforated leather across the upper chest, abdomen, and thighs works with lightweight Matryx torso panels to promote airflow, particularly when the suit is used with compatible Tech-Air 5 or Tech-Air 10 Airbag Systems. HRSF stretch inserts at the crotch, back of the legs, inner arms, and chest further support an unrestricted riding position.
Protection is provided by integrated GP-R armor at the elbows, forearms, knees, and shins, along with Nucleon Race shoulder armor and GP DFS sliders at the shoulders, elbows, and knees. The Tech-Air Ready design supports convenient integration with Alpinestars Tech-Air 5 and Tech-Air 10 systems, and a forearm pocket accommodates the Tech-Air 10 remote LED panel. Soft stretch wrist and ankle cuffs improve comfort, while the detachable comfort liner features a biostatic Polygiene treatment to help maintain freshness during repeated use. The manufacturer is Alpinestars, and the manufacturer and vendor part number is 3150523132156.
