THE NORTH FACE Mountain Down Jacket Size M: Length 77cm, Width 61cm, Shoulder Width 51cm, Sleeve Length 63cm Product number: ND91837 Color: Black Material: 70D GORE-TEX 2L (Outer: 100% nylon, Lining: ePTFE) <Insulation> 600 fill down (80% down, 20% other feathers) Purchased in 2019 from an authorized retailer. If it's a fake (which is impossible), I will give a full refund. At the time, it was a very popular model, along with the Baltro, and sold out immediately online and in stores. I think it's relatively easy to get now. I went through a lot to get it back then, so I didn't wear it much, only 3 or 4 times, and then stored it carefully.
