This is an ISUKA compression bag. It can be used to compress and store items such as sleeping bags. I received it from my family and have been using it, but I'm selling it because I don't use it often. - The thread on the straps is frayed (photo 2). - The coating on the underside of the lid (black) is peeling (photos 5 and 6). - The green fabric has a sheen (photo 7). Below is the product information from Amazon. Fabric: 100% nylon Size: Diameter 15 x 40cm Weight: 120g Color: Green I hope to sell this to someone who understands that it is a used item. Please refrain from purchasing if you are looking for a pristine item. #Stuff Sack #ISUKA #Ultralight
