Great pack. I used it once on a day hike and a couple times casually. I was able to pretty securely strap items onto it and still keep it stable. Initially the straps chafed my pits a bit, but moving the sternum strap down fixed it. The construction is superb and seems like it would last quite awhile. The bungee straps on the outside are especially useful.
I actually ended up returning it since it was actually just a bit too small for my purposes. I was hoping to be able to fit a 13" MacBook Air in it along with a flexible binder, water, warming, and etc. It fits the Mac well but because the shape is narrow it distorts the shape in a way that causes everything else to not fit so well. For the price I was hoping to have a goto pack for everything.
