ALPINESTARS GP Plus R v4 Airflow Leather Jacket - Black/Red/White - US 40 / EU 50 3100624-1321-50

Track days and high-speed road riding demand gear that keeps you cool without compromising protection—the ALPINESTARS GP Plus R v4 Airflow delivers exactly that. Its race-derived ventilation system and advanced stretch materials provide unrestricted mobility and breathability during intense sessions, while strategically placed armor ensures you're protected when it matters most. This is purpose-built equipment for riders who refuse to choose between comfort and safety.

The GP Plus R v4 uses Alpinestars' A-CS Plus stretch technology—a proprietary composite material capable of 30% elongation with 300% tear resistance—allowing the jacket to move with your body while maintaining structural integrity under stress. Perforation zones at the shoulders and chest, combined with a mesh comfort liner, create maximum airflow without sacrificing coverage. The pre-curved sport fit and technical stretch panels eliminate dead zones that trap heat, keeping you cooler during extended high-performance riding.

Protection is engineered with dual-density DFS shoulders, GP Lite elbow armor, and Nucleon Flex Plus shoulder armor—all proven in professional racing. The extended back panel and integrated back protector pocket add coverage without bulk. For riders using active safety systems, this jacket is Tech-Air 5 and 3 Ready, offering compatibility with Alpinestars' airbag technology.
