The Alpinestars AST v3 Air Jacket is a sport-oriented motorcycle riding jacket designed to provide dependable airflow, mobility, and comfort in warm-weather riding conditions. Its dual-tech mesh construction and strategically placed laser perforations promote continuous ventilation across the chest, back, and sleeves, helping riders stay more comfortable during extended rides. The black, dark gray, and red fluo color combination delivers a distinctive sport-inspired appearance, while the Medium size offers a performance-oriented fit for compatible riders. This Alpinestars jacket is identified by manufacturer and vendor part number 3300426-1051-M.
The AST v3 Air uses a multi-panel 450D polyfabric chassis for a balance of strength, comfort, and abrasion resistance. Two-dimensional mesh stretch inserts across the front, sleeves, and back improve airflow while supporting freedom of movement. Additional stretch panels along the torso and upper back help the jacket adapt to the rider’s position, particularly when riding in a forward-leaning or racing crouch. Pre-curved elbows help reduce fatigue, and the elongated rear profile adds coverage and wind protection in the riding position. Cuff and waist adjusters allow riders to fine-tune the fit over riding gear.
Functional details are integrated throughout the jacket for everyday motorcycle use. The aerodynamic cuff design is shaped to reduce pressure and drag while working comfortably with Alpinestars gloves. A low-profile, no-flap collar helps reduce neck pressure, helmet chafing, and material movement at speed. Interior and exterior pockets provide convenient storage for essential items. Strategically positioned accordion stretch panels are designed to accommodate an Alpinestars airbag system while maintaining an anatomical fit when the system is not installed. The jacket is Tech-Air 7x, Tech-Air 5 PLASMA, and Tech-Air 3 ready, making it a versatile choice for street riders and sport-focused motorcyclists seeking airflow, protection-focused construction, and airbag-system compatibility.
