ALPINESTARS GP Plus R v4 Airflow Leather Jacket - Black/Black - US 46 / EU 56 3100624-1100-56

If you're serious about track days or spirited road riding, thermal management and protection are non-negotiable. The ALPINESTARS GP Plus R v4 Airflow cuts through the compromise between safety and comfort by delivering race-proven armor without the heat penalty of traditional leather jackets. Built for riders who demand maximum ventilation without sacrificing impact protection, this jacket combines Alpinestars' decades of motorsport engineering with practical everyday wearability.

The A-CS Plus stretch panels are lighter and more breathable than conventional leather while maintaining exceptional durability—9% weight reduction paired with 300% tear resistance and 600% cut resistance means you get mobility without sacrifice. Pre-curved arms and a sport fit eliminate bunching and restriction, while vented shoulders and perforation zones channel air exactly where you need it during aggressive cornering or highway cruising.

Protection comes integrated: dual-density DFS shoulders control friction on slide, GP Lite elbow armor absorbs impact forces, and Nucleon Flex Plus shoulder armor disperses energy across a wider contact area. The mesh interior liner and extended back cut accommodate aftermarket or OEM protectors, while Tech-Air compatibility adds another layer of safety if you choose to upgrade.
