The cubicbag messenger M 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 medium is worn over the shoulder using the long strap. The shoulder straps are made of leather and positioned for a comfortable fit. This messenger bag is suitable for work and study, and is especially suitable for bicycle transport. The messenger bag's distinctive and clean shape is based on 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's especially useful for laptops (up to about 13 inches). Inside, there's an inner pocket with two compartments that can easily 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. Its unique shape and functionality make the cubicbag messenger medium a design object with high usability.
