Alpinestars Stella SMX Air Jacket

Women's mesh sport jacket with MX roots

The Stella SMX Air is Alpinestars' women's street sport jacket for warm climates, with a mesh chassis over the abdomen, back and inner arms, 450D polyfabric on the outer arms and shoulders and perforated 450D across the upper chest. Polyamide stretch panels on the back, shoulders and sides give it an adaptive fit and the expansion room a Tech-Air 5 airbag needs, and a detachable windbreaker liner cuts the airflow when you don't want it. Protection is DFS Lite external shoulder sliders with Nucleon Flex Plus CE Level 1 armour at the shoulders, elbows and forearms, and it's ready for the long back protector insert. Certified to EN17092-4 A class and Tech-Air ready.

The Stella SMX Air Jacket features a main chassis constructed from mesh on the rider’s abdomen, back and inner arms, paired with 450D polyfabric reinforcement on the outer arms and shoulders. The Stella 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 high-density stretch material on the upper back. The stretch material provides an adaptive fit and a high level of freedom of movement, as well as offers the perfect expansion ability for use with the Tech-Air® 5 Airbag System. As the Stella SMX Air Jacket has been designed to provide premium ventilation, the jacket also comes with a detachable windbreaker liner to help reduce airflow when it’s not needed, offering optimal climate comfort and versatility. DFS Lite external shoulder sliders paired with Nucleon Flex Plus CE Level 1 shoulder, elbow and forearm armour together provide impact protection for the Stella SMX Air Jacket, resulting in a CE level A rated jacket overall. Derived from Alpinestars’ MX DNA, the highly ventilated, Stella SMX Air Jacket is the perfect choice for the every-day commuter and weekend rider looking for a versatile and protective street sport jacket for riding in warm climates.
