I received this backpack from an acquaintance who purchased another one after using it a few times. As a result, I haven't used it, and it seems unlikely that I will, so I'm putting it up for sale. As you can see in the photos, there is almost no dirt, so it appears to have been used only a few times. If you have any areas of concern, please contact me, and I will take additional photos. Brand: Montbell Model: Alpine Pack 50 Capacity: 50L Color: Black
