We cut this suit jacket with warm weather in mind, picking a beautiful, certified-European linen fabric and leaving the back unlined so it stays cool. Look closely: we love this fabric's subtle blue windowpane pattern. Sport Coat Fit: We updated our Tailored Slim Fit for a more laidback and slightly less form-fitting silhouette for ultimate versatility. European Flax™: This guarantee of traceability for premium linen fiber grown in Europe—a natural and sustainable fiber, cultivated without artificial irrigation and GMO-free. Notch lapel with 2-button front. Three exterior pockets, two interior pockets. Single back vent. Lined sleeves, shoulders, and front body, unlined at back for better breathability.
