Middle-size, stylish backpack.
We use there two kinds of leather: the thicker on the front&back walls, front pocket and shoulder straps; and the softer one on the sides of the backpack and on the soft part of shoulder straps. This backpack closes with a metal zipper (two pullers) and latches with stud closures.
Those latches may fix backpack if it is not full, so that the width on the top would be smaller. The main attention was paid to the front pocket (it is structured and has geometric relief) and shoulder straps (they are wide and soft here). Straps are adjustable straps with stud closures.
