I have a nice shape Genuine Leather motorcycle jacket for sale. It has a removable Thinsulate liner. I used this for a year or so and then decided it was too small. My Wife then used it the few times we rode together. The chest of the jacket measures 42in. but would recommend a bit smaller actual measurement for comfort. I would say its in the small to medium size. feel free to let me know with any questions or more/different pictures. Thanks, Justin
