Lightweight Slim Fit Long Sleeve Thumb Hole Down Jacket Activewear gym workout

The jacket is worn only once because it is too long for my liking. It is size M, but fits S. For reference the mannequin without hands is a standard size S and the other one is XS. I am 5’2” and 110lbs and it fits me well. It’s lightweight, warm, it has down filling, 2 side pockets with zipper closure and thumb holes. The sleeves have stretch. It is kept in a vacuum bag together with other clothes that I don’t wear and it might have detergent scent. Please ask for all the details necessary before you purchase!
