The ALPINESTARS SMX Air Jacket in Medium is a highly ventilated street sport jacket designed for warm-weather riding. Its tech mesh chassis uses mechanical stretch with perforated 450D polyfabric in key areas, including the chest panel, to support airflow while maintaining an adaptive fit. Extended polyamide stretch material across the rider’s back, shoulders, and sides, along with strategic stretch inserts on the side torso and upper back, supports sport movement and flexibility.
The jacket is Tech-Air® ready and provides expansion capability for use with the Tech-Air® 5 Airbag System. Its inner construction is prepared for Nucleon protection insert upgrades and is ready to accommodate the new Alpinestars long back protector insert. DFS Lite external shoulder protectors are included as part of the jacket’s protective design. Waist adjusters help refine the fit, while the ergonomic construction supports freedom of movement for everyday commuting and weekend riding.
For changing conditions, the jacket features a detachable windproof liner to help reduce airflow when needed and support climate comfort. A waterproof compartment adds practical storage for riding essentials. The ALPINESTARS SMX Air Jacket is finished in Dark Gray, Black, and Orange Fluo. Manufacturer part number: 3306523-914-M.
