A leather backpack is a classic, yet functional, piece of luggage. They are also an essential for any professional looking to impress at meetings and conferences.
A good leather backpack is made from high-quality leather. It should not be shiny or plastic-y, but soft to the touch and flexible. The stitching should be neat and tight, as should the shoulder straps. Look for a model with multiple pockets on the inside and outside to keep everything you need easily accessible.
