I love this backpack! It has been such a great bag. Comes with dust bag and extra strap, the straps also detached, so you can wear it multiple different ways. Unfortunately, the zipper is not wanting to zip up anymore, could be an easy fix. I just don’t have time to figure that out. I also am not sure on authenticity, hence the price. Great condition other than zipper and honestly the leather is so structured that it still holds close on its own
