SMX Air Jackets Alpinestars A motocross inspired textile jacket, the SMX Air Jacket features a main chassis constructed from tech mesh on the rider's abdomen, back, and inner arms, paired with 450D polyfabric reinforcement on the outer arms and shoulders. The SMX Air also incorporates perforated 450D polyfabric on the upper chest for excellent levels of airflow during the warm, summer riding months. Extended polyamide stretch material has been incorporated on the rider's back shoulders and sides, with a highdensity stretch material on the upper back. The stretch material not only provides for an adaptive fit and freedom of movement, as well as offers the perfect expansion ability for use with the Tech-Air 5 Airbag System. As the SMX Air Jacket provides premium ventilation, the jacket also comes with a detachable windbreaker liner to help reduce airflow when it's not needed, providing optimal climate comfort and versatility. DFS Lite external shoulder sliders paired with Nucleon Flex Plus CE Level 1 shoulder, elbow, and forearm armor provide impact protection providing the SMX Air Jacket with a CE level A rating overall.
