The cubicbag rucksack two S 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 20% new convertible top material was used. The material is virtually waterproof, colorfast and dimensionally stable, i.e. it does not wear out.
The cubicbag rucksack two is carried on the back by the two long leather shoulder straps. The cubicbag rucksack two S is suitable for work and leisure, and especially for transport on the bike. The special and clear shape of the backpack results from the principle of folding.
Unfilled, it is flat and can be stored in a space-saving way. Filled, the backpack unfolds at the bottom. The asymmetrical cut at the bottom ensures that the contents do not press into the back, but fall outwards. The flap folds down completely and is closed with two metal pull closures to make it almost waterproof. The contents of the bag are thus optimally protected even against heavy rain, a feature that particularly protects notebooks (up to about 13 inches) or tablets. Inside, there is an interior pocket that holds a cell phone, notebook and wallet.
On the outside back is a zippered compartment that extends over the entire surface of the backpack. Due to the special shape and functionality cubicbag backpack two S is a design object with high usability.
