The ALPINESTARS SMX Air Jacket is a highly ventilated street sport jacket designed for everyday commuting and weekend riding in warm climates. Its tech mesh chassis combines mechanical stretch with 450D perforated polyfabric in key areas, including the chest panel, to promote airflow while supporting rider mobility. Extended polyamide stretch material across the back, shoulders, and sides, along with strategic stretch inserts on the side torso and upper back, provides an adaptive fit and freedom of movement.
The jacket features an ergonomic design for sport movement and flexibility, waist adjusters, DFS Lite external shoulder protectors, and an inner construction prepared for Nucleon protection insert upgrades. It is also ready to accommodate the new ALPINESTARS long back protector insert and is Tech-Air® ready, with stretch material offering expansion capability for use with the Tech-Air® 5 Airbag System. A detachable windproof liner helps reduce airflow when additional coverage is needed, while the waterproof compartment adds practical storage for riding essentials.
