The Alpinestars Tech-Air Ready GP Plus v4 leather suit is a race-focused one-piece suit designed for sport and track riders seeking advanced materials, dependable protection, and an adaptable fit. Finished in black and white, this model is sized US 46 / EU 56 and combines Flex Plus racing bovine leather, Alpinestars Composite Stretch Plus material, Matryx panels, HRSF stretch inserts, and GP Dynamic Friction Shield sliders. The manufacturer and vendor part number is 31505231256.
The specially refined Flex Plus race leather provides a highly adaptive fit with enhanced comfort, rider feel, and freedom of movement. It meets Alpinestars professional racing standards for abrasion and tear resistance while weighing less than standard bovine leather. A-CS Plus stretch material adds increased elongation and tear resistance compared with leather, while offering a lower-profile alternative to traditional leather accordion panels. Strategically positioned stretch panels across the side torso and shoulder blades help support a natural riding position without compromising coverage.
Ventilation is supported by perforated leather across the upper chest, abdomen, and thighs, along with lightweight, breathable Matryx panels on the torso. These materials are especially useful when the suit is worn with compatible Alpinestars Tech-Air 5 or Tech-Air 10 airbag systems. The suit is fully Tech-Air Ready and includes a forearm pocket for the Tech-Air 10 remote LED panel. Protection comes from GP-R armor in the elbows, forearms, knees, and shins, along with Nucleon Race shoulder armor and GP DFS sliders at the shoulders, elbows, and knees. HRSF stretch inserts are placed at the crotch, backs of the legs, inner arms, and chest for added mobility. Soft stretch wrist and ankle cuffs improve comfort, while the removable liner features biostatic Polygiene treatment to help maintain freshness during repeated use. This Alpinestars GP Plus v4 suit is a strong fit for riders who want professional-grade race construction and Tech-Air compatibility in an upper mid-level track suit.
