ALPINESTARS SMX Air Jacket - Black - 3XL 3306523-10-3XL

If you're logging serious track time or pushing hard on warm-weather rides, airflow and impact protection aren't luxuries—they're non-negotiable. The ALPINESTARS SMX Air Jacket delivers the ventilation you need to stay cool while maintaining the armor and safety integration that separates purpose-built gear from compromises. Its Tech-Air® compatibility means you can upgrade to active airbag protection without swapping jackets, giving you a platform that evolves with your performance demands.

Built with a tech mesh chassis and strategically perforated upper chest, this jacket channels air exactly where you need it. The 450D polyfabric reinforcement and DFS Lite shoulder protectors handle abrasion, while Nucleon Flex Plus armor absorbs impact energy. A detachable windproof liner lets you dial in conditions, and waist adjusters ensure a locked-down fit at speed. The upgrade-ready design accepts additional Nucleon protection inserts, so you're not locked into a single configuration.
