The cubicbag messenger up-end medium is made from genuine convertible top fabric, as used in automobile production. On average, 80% of the material used was leftover from convertible top production, and 20% was new convertible top material. The material is virtually waterproof, colorfast, and dimensionally stable, meaning it won't stretch.
The cubicbag messenger up-end is worn over the shoulder using the long strap. The shoulder strap is made of leather and positioned for a comfortable fit. The messenger bag is suitable for work and leisure, and is especially suitable for bicycle transport. The messenger bag's distinctive and clean shape is derived from the folding principle. When empty, it lies flat and can be stowed away to save space. When filled, the bag unfolds to the bottom.
The flap folds completely over and closes with two metal pull tabs, making it almost watertight. This optimally protects the contents of the bag even in heavy rain, a feature that particularly protects laptops (up to about 13 inches) or tablets. The interior features an inside pocket that can accommodate a cell phone, notebook, and wallet.
On the outside back, there's a zippered compartment that extends across the entire surface of the bag. Thanks to its unique shape and functionality, the cubicbag messenger up-end medium is a design object with high usability.
