Whoa! Comfortable, comfortable, comfortable. I just purchased the Whitney and although I thought it was kinda pricey, now I can see why. The waist belt, shoulder harness, and shock absorbing chest strap are all designed with comfort, and more importantly, support in mind. The only reason this backback didn't get a "5" in my book is because the barn door side pockets are kinda funky. I don't understand why Gregory put the compression straps over the tops of the side bags!! Also the front panel pocket is smaller than I anticipated. However the comfort trade-off is more than worth it (note: I'm an organization freak). Highly recommend this pack primarily due to comfort/support; I could have hiked double the miles I'm used to just because I couldn't feel the Whitney on my back!!!! I can tell after just one weekend in the Smokies that this puppy will last forever!!!!
