The Alpinestars SMX Air Jacket is a versatile motorcycle riding jacket designed for warm-weather performance, airflow, comfort, and dependable abrasion resistance. Finished in Black/Anthracite and offered in size 3XL, this sport-fit jacket features a multi-panel 450D polyfabric construction that provides a practical balance of strength, comfort, and protection for street and sport riding. The elongated rear section improves coverage and wind protection while riding in an aggressive or forward-leaning position. The manufacturer part number and vendor part number are both 3306523-104-3XL.
The SMX Air Jacket uses laser-perforated chest panels and 2D mesh stretch inserts across the front, sleeves, and back to promote continuous airflow and ventilation. Strategically placed stretch panels along the torso and upper back support a more adaptive fit while improving shoulder mobility, particularly when riding in a racing crouch. Pre-curved elbows help reduce rider fatigue, while the soft-touch synthetic suede collar and cuffs improve comfort during extended rides. Waist adjusters allow riders to fine-tune the fit for a secure, performance-oriented feel.
A removable windbreaker adds versatility, allowing the jacket to be quickly adapted to changing weather conditions without replacing the entire garment. Accordion stretch panels are positioned to accommodate the expansion of an Alpinestars airbag system while maintaining an anatomical fit when no airbag is installed. The jacket is Tech-Air 7x, Tech-Air 5 PLASMA, and Tech-Air 3 ready, making it suitable for riders seeking compatibility with advanced Alpinestars airbag technology. Interior and exterior pockets provide convenient storage for everyday riding essentials. The Alpinestars SMX Air Jacket is an appropriate choice for motorcycle riders who want lightweight ventilation, flexible sport ergonomics, and adaptable protection for warm-weather road and track-inspired riding.
