Lightweight down vest with excellent heat retention. - Color: Gray - Material: Outer: 100% nylon, Filling: 90% down, 10% feather Thank you for viewing. Size...M The label has faded, I've worn it quite a bit. I usually wear men's M, so I've listed it as M. It shows signs of wear and tear, and has some stains, so I'm selling it at a low price. Would it be suitable for workwear? Measurements (laid flat): Width: 51cm Length: 61cm Please note that there may be some margin of error.
