ALPINESTARS GP Plus R v4 Leather Jacket - Black/White - US 40 / EU 50 3100524-12-50

If you're serious about track performance or high-speed riding, your safety gear needs to match your commitment. The ALPINESTARS GP Plus R v4 delivers race-proven protection with the mobility and comfort required for extended sessions—whether you're pushing lap times or enjoying spirited road riding. Built with materials and armor systems trusted by professional racers, this jacket gives you confidence when it matters most.

The A-CS Plus stretch leather moves with you, not against you, while the integrated Nucleon Flex Plus armor and GP-R Lite extended elbow protection absorb impact energy where you need it. Dynamic Friction Shield shoulder sliders reduce abrasion forces during slides, and the detachable thermal vest adapts the jacket to seasonal conditions. Long airflow vents keep you cool during intense riding, and Tech-Air ready compatibility means you can add an active airbag system for an extra layer of protection.
