This is my second backpack and I love them.  The only thing that stops it from getting 5 stars is that the straps slip off my shoulder.  SO...i found purse gummys....don't have them yet but I have a suspicion they will solve my issue with this bag and others.  This bag is great for traveling...secure, light weight, and has a cool zippered compartment on the back that I keep my wallet in for easy access and security.  Pros:  Light weight, configuration, use of materials, durability.  Cons:  straps slip, I'd prefer magnetic snaps vs regular snaps.
