The Montblanc Sartorial Jet collection combines clean elegance and lightness, thanks to a combination of black saffiano-print calf leather and plain water- and scratch-resistant black nylon fabric with a satin finish. The Backpack Medium can be carried using the two adjustable branded nylon shoulder straps or the leather-covered single handle on top. It can also be attached to a trolley's handles by using the satellite system. The outside is equipped with two side zipped pockets while the main compartment is closed with two buckles and a drawstring. Its spacious internal organisation can accommodate A4-sized documents along with a laptop in the open padded pocket, two writing instruments in the leather loops and other personal belongings in the two pockets - one with zip and one open - on the sides.
