A motocross-inspired fabric jacket, the SMX Air Jacket features a main frame made from technical mesh on the rider's abdomen, back, and inner arms, combined with 450D poly-fabric reinforcement on the outer arms and shoulders.

The SMX Air incorporates perforated 450D polyfabric on the upper chest for excellent airflow levels during the warm summer riding months.

Extensive stretch polyamide material has been incorporated into the rear shoulders and sides of the rider, with high-density stretch material on the upper back. The stretch material provides an adaptive fit and freedom of movement.

The SMX Air Jacket provides top ventilation and also features a removable windproof lining to reduce airflow when not needed, providing optimal climate comfort.
