I really like having the weight low, by my hips and not on my shoulders. Really improves my center of gravity and balance. The back stays in place well and has good storage. It even has small pockets on each side that you can get to without taking it off. The only trouble I had was figuring out a way to get the reservoir to air dry when not using it. I used a small vase that will hold it open while drying.
