It is a practical bag back, solid and functional offering a sizable storage capacity thanks to its many external and internal pockets. Good protection for a laptop. The rear part of the bag is reinforced on four points, leaving a space that allows ventilation between the bag and back. The handle is reinforced, the straps are padded and can be adjusted, the finishes are of quality. The backpack vacuum weighs 1.4kg. It is an article which I am satisfied.
