ALPINESTARS SMX Air Jacket - Black/Red - XL 3306523-1303-XL

When temperatures rise, most riders face a choice: sacrifice airflow for protection, or compromise safety for comfort. The ALPINESTARS SMX Air Jacket eliminates that trade-off with a tech mesh construction engineered to maximize ventilation while maintaining the impact protection you need for serious riding. Whether you're logging miles on summer commutes or pushing hard on weekend track days, this jacket delivers the breathability and versatility that warm-weather riders demand.

Built on a foundation of 450D polyfabric reinforcement with strategically placed perforated panels, the SMX Air prioritizes airflow without sacrificing coverage. The polyamide stretch material and stretch inserts conform to your body for unrestricted movement, while the detachable windproof liner adapts to variable conditions. Alpinestars equipped this jacket with DFS Lite shoulder protectors and Nucleon Flex Plus armor—proven impact-absorption technology that keeps you protected when it matters most. The Tech-Air 5 compatibility adds an optional layer of safety, and the customizable waist adjusters ensure a locked-in fit across different body types.
