The Alpinestars GP Plus R v4 Rideknit Leather Jacket delivers elite track-derived technology engineered for demanding sport and street riders. Constructed from race-grade, highly abrasion-resistant bovine leather, this jacket incorporates proprietary Rideknit® stretch paneling under the arms, along the inner sleeves, and around the torso. Extensive localized perforations across the main chest and sides work in tandem with the breathable knit sections to provide maximum ventilation and thermal regulation during high-speed summer riding.
Built with uncompromising safety and movement in mind, the GP Plus R v4 is Tech-Air® Ready, designed to seamlessly house Alpinestars airbag systems. External Dynamic Friction Shield (DFS) shoulder sliders work alongside internal CE-certified armor to manage impact and slide protection. Finished with pre-curved arm geometry, an ergonomic low-profile collar, adjustable waist cinch tabs, and bold high-contrast ASTARS chest graphics, it represents the modern pinnacle of sport leather performance.
