I'm looking for a thin, single-layer tailored jacket that won't feel overwhelming for commuting in the late summer heat.

Single-layer tailored jackets without a lining are not in the data. Instead, I've selected a buttonless tailored jacket with a neat silhouette that's great for commuting, as well as linen-cotton blend cropped jackets. Please note that all three products come with a lining.

Among the jackets containing linen, I've picked a double-breasted blazer, a light cropped blouson, and a casual work jacket. The double-breasted blazer and the work jacket are a cotton-linen blend, while the cropped jacket is 100% linen fabric. Please take a look based on your preferred silhouette and length.

Neat, classic tailored blazers are currently not in the data. Instead, among the jacket-style options, I've selected a V-neck one-button design jacket, a cropped jacket that can be styled with an open collar, and a black work jacket. Please note that all three products feature cutoff finishes or casual silhouettes.
