I have purchased three Healthy Back Bags in the last 10-12 years. The only complaint I have is with the zipper. Had the zipper not failed in my first bag, I would still be using it. This is a great bag, LOTS of room, easy to keep organized and almost like a briefcase. (I guess that's why the zipper broke on my first two.)
I would highly recommend this bag. Just be carefull not to overstuff it!
