Product Review (submitted on July 16, 2014):
Review by Robert J. Hughes for Rating: I have a couple of these in dfeefrint sizes. They fit on the same frame so you only need one, if you want one at all. I like a frame because it keeps the bag off of my back and I am much cooler when I hike which is big here in Florida. The quality of the bag is excellent with plenty of easy to get at compartments. I would highly recommend it.
