I'm not very familiar with it, but it's a Levi's 3rd type denim jacket. I purchased this product about 30 years ago at a local jeans shop. I've had it at my parents' house for a long time, but I'm selling it because I don't seem to be using it. I haven't worn it much, and the color fading is still quite visible. The size is 42, which is about L to XL. The button back stamp is J22. The product label seems to have been cut off, as it's not there.
