This messenger bag is one of the most amazing bags I have ever owned. It is made of a canvas material, but is very light weight. It holds so much and has special pockets for extra items so these items won't get lost. There is even an anti theft zipper compartment. The handle on top is stitched very tightly and is very sturdy. The strap is adjustable and can be used either as a shoulder bag or longer for use as a messenger bag. The material feels so soft and smooth yet it is so very sturdy. Durable and reliable, can be used for school, traveling or even as a camera bag. It also has a really cool retro design. This is really a neat bag.
