ALPINESTARS SMX AIR MEN’S JACKET – BLACK / BRIGHT RED
The SMX Air Sport 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. Perforated 450D polyfabric panels on the upper chest provide excellent airflow during warm summer rides.
Extended polyamide stretch material has been incorporated on the rider’s back, shoulders, and sides, with a high-density stretch fabric on the upper back to ensure an adaptive fit and superior freedom of movement. The stretch zones also offer ideal expansion for use with the Tech-Air® 5 Airbag System.
Designed for maximum ventilation, the SMX Air Jacket also comes with a detachable windbreaker liner, allowing riders to adjust airflow and maintain comfort across changing conditions. DFS Lite external shoulder sliders and Nucleon Flex Plus CE Level 1 armour on the shoulders, elbows, and forearms deliver proven impact protection. Derived from Alpinestars’ MX DNA, the SMX Air Jacket is perfect for everyday commuting and weekend rides in warm climates.
