The Alpinestars AST v3 Air Jacket delivers lightweight ventilation, dependable abrasion resistance, and a performance-oriented fit for warm-weather motorcycle riding. Finished in Black, Dark Gray, and White, this 4XL motorcycle jacket uses a multi-panel 450D polyfabric construction for a balanced combination of strength, comfort, and durability. The sport fit features an elongated rear for improved coverage and added wind protection when riding in a forward position, while pre-curved elbows help reduce fatigue during extended rides. This jacket is designed for motorcycle riders seeking airflow and mobility without sacrificing practical protection features.
The AST v3 Air Jacket combines extensive laser perforations across the chest, back, and sleeves with 2D mesh stretch inserts positioned throughout the front, sleeves, and back. These ventilation zones promote continuous airflow and climate control, while stretch panels on the torso and upper back provide an adaptive fit and improved shoulder mobility. Strategically placed accordion stretch inserts accommodate compatible Alpinestars airbag systems, allowing the jacket to expand during airbag inflation while maintaining an anatomical fit when the system is not installed. Cuff and waist adjusters help fine-tune the riding fit, and the aerodynamically engineered cuffs are designed to reduce drag while pairing comfortably with Alpinestars gloves.
Additional riding-focused details include an integrated low-profile collar that helps minimize neck pressure, helmet chafing, and flapping at speed. Interior and exterior pockets provide convenient storage for everyday essentials. The Alpinestars AST v3 Air Jacket is Tech-Air 7x, Tech-Air 5 PLASMA, and Tech-Air 3 ready, supporting integration with selected Alpinestars airbag systems. The manufacturer part number and vendor part number are both 3300426-102-4XL. This jacket is sized 4XL and is intended for street, sport-touring, and warm-weather motorcycle applications where airflow, flexible movement, and compatible airbag readiness are important.
