A softly slubbed wool weave patterned in a plaid of dusky blues furthers the casual versatility of a sport coat crafted with a lightweight feel that's ideal for warm-weather and semiformal occasions. Softer construction in the shoulders and a subtly fitted waist provide a relaxed silhouette that pairs well with your less-formal formalwear.

Fabrication: Wool is the most common of suiting fibers, with durable, flexible properties that help formalwear maintain its shape. Naturally breathable and water-resistant, wool retains heat when it's cold and vents heat when it's warm.

Formality: Semiformal and elevated-casual occasions that require you to look on the relaxed side of well-dressed, including daytime events, business-casual meetings, work travel and social functions
