This is a Final Home multi-zip survival nylon jacket. It's a very convenient and innovative concept, allowing you to pack it with items while traveling, making it function like a down jacket. My father bought this at the time but never wore it, keeping it hidden away. The size is XS, but it's large, and I think it's about a M or L. It's new, unused, and comes with the tags! Shoulders: 56cm Length: 75cm Sleeves: 55.5cm Chest: 58cm I've found something I want more than this clothing item, so I'm letting go of my collection. Please feel free to comment if you have any questions. Thank you!
