I purchased this but never used it, and it's been stored at home. Therefore, it's an unused item, but I've classified it as "near mint" condition, as it's close to being unused. Size is M, but please refer to the images with the measuring tape to determine the size. It looks like it could also be a vest, but the sleeves are attached. I listed it as golf wear, but it might not actually be for golf. Please check the images and consider purchasing.
