Blue backpack cover made of water-resistant nylon, silver on the inside, suitable for up to 40L. There are some fold creases, but it has not been exposed to rain and has been stored unused for a while. There is no hydrolysis, and it is in a clean condition. I measured the approximate dimensions with a measuring tape: Length 70cm, width 40cm, gusset 20cm approximately. A rubber band is sewn around the perimeter, so I cannot give you the exact dimensions, but please use this as a reference. Shipping will be done by compressing it in a folded state. - Color: Blue - Model Name: Rucksack Cover 40 - Material: Nylon - Inside Color: Silver Thank you for viewing.
