This is a Patagonia packable backpack. It's ultra-lightweight and can be folded compactly for carrying. I purchased it at a Patagonia store about 10 years ago and only used it as a sub-bag on a week-long trip. I haven't used it since. Current models are mainly tote bag style, but I remember this was the only shape available at the time. As shown in the fourth photo, the plastic fastener on the inner cord of the outer flap is broken and missing, so I've been using it tied with a string. The condition shows overall signs of use, but there are no significant scratches or damage, and I think it can still be used for a long time.
