Vintage Lee Rider 101J dated to the 1970s. Union made in the USA. There is no tagged size, I estimate the size to be a 44 (with a 46 chest, 23” pit to pit, please see photos for exact measurements). Would fit a regular large or a roomy medium, I am a size 40 and wore it comfortably with a hoodie/flannel layered underneath for one winter. Some of the stitching is coming loose underneath the right armpit (see photos). Really terrific jacket, I’m selling because I plan to size down one size in the future. Please reach out if you have any questions, thank you!
