I had purchased one of these backpacks for work several years ago and loved it's roominess. As an NDT tech, I carry lots of work related stuff in my backpack and loved how it had room for my gear. I was saddened when a zipper finally wore out so I couldn't use it. I have tried a couple of other backpacks in the last year or so and nothing has the room that this one does. I was glad I was able to get a new one even though Ogio had discontinued it.
