Rated 5 out of 5 by from WOW I had already ordered this pack when I went to a store and tried it on but I was really on the fence as to whether or not the new suspension would be worth the hefty price tag. I dropped twenty five pounds in the main compartment, put the pack on, and I was immediately impressed. Even just in taking a few steps the pivoting hip belt made the pack feel incredibly light because it was allowing me to move so naturally and I could feel my back staying really relaxed. No one was around so I quickly jumped up on and then off the table by the backpacks a few times and, WOW, that's when the significance of the 1.5" of float in the back hinge started to hit me. I don't know if I can do it justice in a short review but the way the pack moves with your body when you stretch and twist is a revelation. You just have to put one on and see. I've only had my Bora 50 for a few weeks so I haven't put many miles on it yet but I bought my first Arc'teryx pack (small daypack, Arro 22) 17 years ago and it's still going strong so I know these things are built to last. This is the most excited I've been about a product for a long time. I think the paradigm just shifted.

Rated 5 out of 5 by from Best Pack on the Market! I recently purchased this pack and received it in the mail a few days ago. As others report, and which I can confirm, the pack's suspension system is truly a game-changer. The ability to move with the pack, but without displacement of weight from your hips or the pack riding up from your hips during movements while scrambling or climbing, is absolutely phenomenal! Further, the materials used to construct the pack are bombproof and very likely waterproof. My last backpack of this size was an original Osprey pack (when the packs were made in Delores, CO) over 20 years ago. This new offering from Arc'Teryx may result in the retirement of my beloved Osprey. One additional note: if you are tall like me (6'6") and require a pack to accommodate a longer torso length and broader shoulders, I would highly recommend this pack because of its unique ability to dial in the fit based on specific placement of the shoulder straps.

Rated 5 out of 5 by from Incredible Pack I bought a Bora pack in 2001 (I think), and carried it all over the US and Europe. It was the most durable and comfortable pack I had, more so than more recent purchases. When I finally went to replace it a couple of years ago, I was disappointed the Bora was no longer made, so I bought an Altra pack, which I love. When I saw the new Bora I got it and just finished by first trip (35 lbs packed weight). It is amazing comfortable. First day was 15 miles over moderate terrain, with some scrambling. The hip belt allowed me wonderful freedom of movement, while keeping the pack from shifting on my back. My friends also noted that I was moving a lot faster than normal, due to the natural gait allowed by the pack's suspension. We got rained on, and everything in the pack stayed perfectly dry. The stiffness of the material on the top of the pack can make it a little difficult to dig for small items in the top, but that's a very minor complaint. The straps and attachment points on the Bora are very well designed and make sense when fumbling with them in the dark. It is a somewhat minimalist pack, so there are not a multitude of pockets, but it packed everything I needed for a multiday trip in cool weather with room to spare. Overall this is an incredible pack, and has become my new standard carry pack.

Rated 5 out of 5 by from Great Backpack I was a little hesitant to buy this backpack since it is up there in the price range. I decided to go for it after I saw it at a store. I took it on its first trip to the Pecos Wilderness and it felt amazing. I did not have the soreness on the shoulders, and I did not feel the normal sweaty back that many other backpacks have left me (I have to say that I sweat somewhat profusely). The ventilation was superb. The external materials are great! We got lost for a while and had to walk through dry/burned trees and the backpack performed great. The straps are super soft and cushiony and I really appreciated that since I am a bit muscular and have a broad chest, so straps are always an issue for me. The internal materials of the backpack are also super! It feels a bit plasticky, which may be an issue for some people, but for me it is not really a concern. I really liked the kangaroo bag. The Rotoglide works fantastic. It feels a bit different when you use it for the first time, but after a while you get used to it and don't even notice it. It really helps control the backpack and it really stays in place when you are climbing steep terrain. You do not feel the sideways motion of many other systems. This backpack is a bit heavier than other packs I have tried, but with the suspension system you do not really notice the weight. In my view, the only downside is the very steep price; so if you have the means to afford this give it a try. After trying this backpack I fell in love *heart heart*; I think that I will use it almost exclusively for my upcoming backpacking trips.
