The Alpinestars AST v3 Air Motorcycle Jacket combines lightweight ventilation, abrasion-resistant construction, and sport-focused ergonomics for warm-weather street and touring riders. Finished in Black, Dark Gray, and Red Fluo, this 4XL jacket features a multi-panel 450D polyfabric chassis designed to provide dependable strength, comfort, and abrasion resistance. The AST v3 Air model is built for motorcycle use and offers a sport fit with an elongated rear section for improved coverage and wind protection while riding in a forward-leaning position.
Extensive laser perforations across the chest, back, and sleeves work with 2D mesh stretch inserts on the front, sleeves, and back to promote continuous airflow and climate control. Stretch panels throughout the torso and upper back provide an adaptive fit and support freedom of movement, particularly around the shoulders during a racing crouch. Pre-curved elbows help reduce fatigue, while adjustable cuffs and waist closures allow riders to fine-tune the fit. The aerodynamic cuff design helps reduce drag and pressure while working comfortably with Alpinestars gloves.
Designed with rider practicality and airbag compatibility in mind, the Alpinestars AST v3 Air includes strategically positioned accordion stretch panels that accommodate an inflating Alpinestars airbag system while maintaining an anatomical fit when no system is installed. The integrated low-profile collar helps minimize neck pressure, helmet chafing, and fabric flap at speed. Interior and exterior pockets provide convenient storage for everyday riding essentials. This jacket is Tech-Air 7x, Tech-Air 5 PLASMA, and Tech-Air 3 ready. Manufacturer and vendor part number: 3300426-1051-4XL.
