The cubicbag rucksack one is made from original convertible top material as used in automobile production. Used for this on average 80% "leftovers" from the production of convertible tops and to 20% was used new convertible top material. The material is almost waterproof, colorfast and dimensionally stable, i.e. it does not wear out.
The shoulder straps are made of leather and are attached in such a way that this results in a good wearing comfort. The unusual shape of the backpack results from the principle of folding. Unfilled, it is flat and can be stored to save space. Fully packed, the backpack unfolds to a baseball-like body with rounded edges.
Metal Loxx pull closures keep the bag closed in any condition. The interior features an interior pocket. The cubicbag rucksack one is suitable for shopping and for trips - by bike, for example. The special shape and functionality make the backpack a design object with high usability.
