This is the BEN DAVIS CLASS DAYPACK. It's a unisex model, and although I've listed it under the men's category, it was actually used by a woman. The capacity is approximately 28L, and it comes with a separate bag-in-bag. It's a convenient size for school, work, days with a lot of stuff, or even short trips. The bag-in-bag inside helps you organize small items and makes them easy to access. I bought it a few years ago, and there are some minor scuffs from use, but no noticeable stains or major damage. Please refer to the photos I've included, which I've taken from the official website, for the size. Feel free to ask any questions you may have. Please only purchase if you understand that this is a used item.
