I love love love this bag! Not only is it roomy, but I love the zippered inner pocket AND I love that the main compartment is zippered as well, making it very very secure. The canvas is of good quality and should make for a long-life. I love the DEEP pockets at both sides of the bag, large enough for carrying a bottle of water, but with the security of a nice snap so I feel confident placing my cell phone and small card carrier that I keep my transportation tickets/passes.  It's an awesome bag!
