I purchased this off Mercari and it a Medium. It fits quite slim and too fitted for my taste :) Excellent used condition, no flaws or stains noted. Nonsmoking home. This sleeveless puffer vest features a dark olive green color and down insulated design for warmth. It includes an attached non-removable hood and a full-length zipper for easy wear. The horizontal quilting pattern adds a stylish touch while providing a slightly fitted silhouette.
