Made of sturdy cowhide leather, these backpacks from Brooks. They have a well-organized interior and are available in two sizes. The highlight: the leather has a continuous fine perforation, behind which a reflective film (Lycra, reflective coated) is discreetly hidden. If light falls on the surface of the backpack, this throws it back to the source and makes the elegant and restrained piece of luggage a striking and highly visible object in road traffic.
