Alpinestars SMX Air Jacket

Derived from Alpinestars' MX roots, the SMX Air Jacket is a highly ventilated street sport jacket for warm climates. A tech mesh chassis on the abdomen, back and inner arms is paired with 450D polyfabric on the outer arms and shoulders, and a detachable windbreaker liner cuts airflow when you don't need it. CE Level 1 Nucleon Flex Plus armor covers the shoulders, elbows and forearms, with DFS Lite shoulder sliders. It's Tech-Air® 5 Ready.

Note: Follow the sizing chart under the fitment tab for the proper fit. These jackets run small compared to traditional US sizing. If you want a looser fit we suggest sizing up one.
