The ALPINESTARS AST v2 Air Jacket is a 4XL motorcycle jacket designed for riders seeking airflow, impact protection and compatibility with the Alpinestars Tech-Air 5 airbag system. Its strategically positioned stretch panels accommodate airbag deployment while maintaining an anatomical fit when the system is not installed. The jacket is constructed from hard-wearing 600 Denier poly-fabric and features extensive mesh panels across the front, back and arms to promote airflow.
Removable Nucleon Flex protectors are fitted at the elbows and shoulders for lightweight impact resistance, while GP Lite shoulder panels provide enhanced abrasion resistance in a key area. Chest and back protector compartments include comfort padding and can accept Alpinestars Nucleon chest and back protectors as accessory upgrades. Pre-curved sleeves support comfort in the riding position, and sleeve volume adjustments help personalize the fit while maintaining elbow protector placement.
The elongated rear profile and hook-and-loop D-ring waist adjustment provide additional riding comfort and customization. Zipped external hand pockets offer secure storage, while comfort-edge materials at the collar and cuffs support moisture-wicking comfort. Reflective details improve visibility, and auto-locking zippers provide durable, secure closures. Manufacturer part number: 3306121-155-4X. Vendor part number: 3306121-155-4X.
