I purchased this pack to travel through Europe and do a few multi-day hikes (Amalfi Coast, Tour du Mont Blanc, etc). What originally sold me on the pack was the frame and how it sits when on your back. That is basically it's only redeeming quality, and why it is 2 stars instead of 1....though you will still sweat, don't let the hype fool you. What I quickly learned was that the frame makes it extremely cumbersome any time other than when it's on your back. On multi-day backpacking trips, I really missed the padding on the shoulders and the hip belt, the loss of hip packs, and lack of a zipper to access the inside without unpacking everything. I also had to buy a separate rain cover, as that was not included in the pack. I'd highly recommend adding a few ozs and keeping the padding that keeps everything else besides the back comfortable!
