Alpinestars GP Plus R V4 Airflow Leather Men's Street Jackets

The GP Plus R v4 Airflow Jacket combines top ventilation with a sport fit and pre-curved arms for superior riding comfort and performance. It features advanced shoulder and elbow protection, and is designed for maximum airflow with vented shoulders and perforated zones. The jacket uses Alpinestars' A-CS Plus technology for stretchable panels that are lighter and more durable than leather, enhancing breathability and freedom of movement. Made from 1.3mm race-grade leather, it ensures both safety and comfort, with extra stretch panels for a snug fit.

This jacket is Tech-Air ready and can accommodate both Tech-Air 5 and Tech-Air 3 systems.

The Tech-Air 5 system decreases impact force by up to 93% compared to a CE-certified passive protector. It offers the same protection as that provided by 18 Level 1 back protectors.

  • 1.3mm race-grade leather construction for optimum abrasion resistance and comfort
  • Vented shoulders and extensive perforation zones on chest and sides for maximum airflow
  • Alpinestars composite stretch (A-CS Plus) technology stretch panels on the torso for exceptional breathability, comfort, and freedom of movement
  • Extensive technical stretch panels under arms, on inner arms, and around the neck
  • Dual-density DFS shoulders for superior friction control
  • GP lite elbow armor, and Nucleon Flex Plus shoulder armor
  • Fully CE-certified riding garment to CE - category II EN17092-3:2020 standard - AA class
  • Colors: Black / Red Fluo / White, Black / White, Black / Black
  • Sizes: 48, 50, 52, 54, 56, 58, 60
