This pack is super comfortable. I have experienced other brands and styles and this is by far the best pack my body has experienced. It feels effortless to carry weight and my back was very happy (I have L4 & L5 disc issues). I took this pack with me on a hiking trip to Costa Rica and it went with me on some pretty rigorous terrain. I highly recommend this pack to anyone with back stress.
