Heavily worn Patagonia Black Hole Backpack. This bag has A Lot of wear! Dinge and dirt on the straps and inside. Some small holes in the elastic side pouches. Paint marks and wear to the outside. These bags have a good reputation for being very durable and someone really tested that with this one! It still functions quite well as a backpack, just not as clean as it once was. It's not marked if it's 25L but we would guess it is. Please take a look at the provided measurements before purchase. 19 1/2 x 10 x 5 Inches
