It doesn't always have to be a barrel of oil. Beer, wine or whiskey can also be stored in barrels - or concentrated and well-thought-out functionality. The Barrel Backpack is made from 100% recycled PET. The coated base material and the well-padded base compartment give the backpack high stability and good weather resistance. An external USB adapter, the padded laptop and iPad compartment, a fold-out partition, a separate removable fabric bag for wet swimming trunks or a pair of shoes, and a special security compartment for the passport are just some of the things whose sole purpose is to make everyday life easier to keep things organized. By the way: The sustainable Barrel from Crumpler holds a whopping 20 liters and weighs just 1350 grams.
