The cubicbag rucksack two S is made from genuine convertible top fabric, as used in automobile production. On average, 80% of the material used was leftover convertible top material, and 20% was new convertible top material. The material is virtually waterproof, colorfast, and dimensionally stable, meaning it won't stretch.
The cubicbag rucksack two is worn on the back using two long leather shoulder straps. The cubicbag rucksack two S is suitable for work and leisure, and is especially suitable for bicycle transport. The backpack's distinctive and clean shape is the result of the folding principle.
When empty, it lies flat and can be stowed away to save space. When filled, the backpack unfolds to the bottom. The asymmetrical cut at the bottom ensures that the contents do not press against the back, but fall outwards. The flap folds completely over and is closed with two metal pulls, making it almost watertight. This optimally protects the contents even in heavy rain, a feature that is particularly protective for laptops (up to about 13 inches) or tablets. The interior features an inside pocket for a cell phone, notebook, and wallet.
On the outside back, there's a zippered compartment that extends across the entire surface of the backpack. Its unique shape and functionality make the cubicbag rucksack two S a design object with high usability.
