It's unlined, quite oversized, and a great khaki color. This jacket is the kind of layer that makes a plain old blazer more cool and more workable in proper winter weather. It's also great to hang on your shoulders over a black cocktail dress to give it a bit more edge. Or wear it belted over black riding pants and chunky lace-up boots.
