This is a North Face backpack. I used it for traveling over 10 years ago, and it's in a very dirty condition. It's quite old, so I don't have exact information, but it's very large, probably over 50L. I hand-washed it, but I think it could be cleaner if thoroughly cleaned. The third photo shows the damaged part (no problem with use). The fourth photo shows that the buckle is not the original one (usable). The fifth photo shows that the inside stains are difficult to remove. I think it's suitable for uses where it's expected to get dirty, such as mountain climbing or backpacking trips. Size: 50-100 L
