I have back issues and so I like this so much better than having weight on my back. And I really like that I can slide it around for easy access instead of having to take a backpack off to access my stuff. It's very comfortable except when it's heavily loaded, the one inch strap across my stomach can put uncomfortable pressure across my abdomen. It would be better if the 1" wide abdomen strap were padded or wider. I am 5'7" and weight 145.
