This is a Mountain Hardwear UL 20-liter foldable backpack. It has been stored in a dark place and is a new item with tags, never used. I opened it for the first time to list it. I have kept the unpacking to a minimum to maintain the initial quality. Please check the product condition in the photos. It will be wrapped in a plastic bag and shipped in a cardboard box. Please refrain from price negotiations. As this is a personal item, please refrain from purchasing if you are overly concerned about minor details. Mountain Hardwear HP Base Material: Nylon, Approximate Weight: 303g Approximate Back Length: 41cm to 56cm
