I've used this pack for a few 3-4 day backpacking trips here in the mountains of Southern California and in Sequoia & Kings Canyon National Park and so far I love it. This pack is extremely comfortable and is easy to configure for a proper fit. The pockets on the hip strap are really convenient and a decent size. I was able to fit my camera (which is older so not very small) in one of those pockets and my sunglasses in the other which was very convenient. I am 5'7" and got the size small. The compartment for the bladder is also a nice feature, making access to my water really convenient. I was also impressed with how much my back did not sweat carrying this thing. Honestly, I still haven't figured out all the straps but I love that I can easily stow my trekking poles and camping pad. I'm looking forward to using this pack for years to come.
