Lightweight and durable nylon Patagonia backpack with adjustable straps. Purchased over 10 years ago, but I'm selling it now as I haven't used it in recent years. There is some dirt and deterioration inside the backpack and on the rubber parts of the shoulder straps (see the red frames in images 10 and 12). The side pockets are also somewhat loose. I used it about 4 or 5 times a month, not every day. I think it's still in good condition and usable, but there may be some oversights, so please only purchase if you understand that it is a used item. I plan to fold it up small for shipping.
