These are great if the zippers hold up. A couple of mind...zipper blew out after only a week of casual use and then Im unable to use. Good price so I made the exception. As for design, these function well. I like the layout of the bag - where the zippers and pockets are, size, ability to change from left to right....2 stars off only because probably 2 out of 5 I can no longer use due to the zipper issues on some of these.
