I purchased this at a sporting goods store a few years ago. I mainly used it for travel, but I haven't been going anywhere lately, so I'm putting it up for sale. The capacity is 26 liters, making it perfect for a day trip. If you don't pack much, you could even use this backpack for a two-night trip. Its simple construction makes it sturdy. It can be used in both urban and outdoor settings. It only has the chest strap; I've lost the other straps, but it should be fine for normal use. There is a dark stain in the space below the logo, as shown in image five.
