Lightweight backpackers are all about “base pack weight:” how light your pack is without consumables like food, fuel and water. If you start with a pack that weighs only 2 pounds, 8 ounces, but can handle multi-day trips with loads up to 40 pounds, you’re headed in the right direction.

I am a longtime Atmos 65 user and was hesitant to get the Exos, worrying that the bag didn't have enough meat on its bones to last in the backcountry. After using it this weekend, I am moving exclusively to the Exos. While reviewing the Exos here, I will also try to compare it to the Atmos. I try to shave weight where I can, which was on of the reasons I gave the Exos a go.
Weight/sizing: I have a 19in Torso so a medium Osprey pack fits me well. The Med Atmos weighs 3lbs 9 oz, while the Med Exos is 2lbs 9oz, so there's a pound saved right there. I would note that like the Atmos, the should strap suspension (i.e. the torso lenth) is not adjustable, as it is on the Talon series.
Straps/buckles/zippers: much smaller/thinner on the Exos, which is how Osprey was able to save weight. The zipper pulls are smaller, the straps are notably thinner (especially the side compression straps). Having said that, the straps appear to be just as durable as the thicker Atmos straps and I did not have an issue at all. I was shocklingly surprised how comfortable the shoulder straps were, too. While they have a little less padding than the Atmos, there was no sacrifice in comfort. Wait belt looks slighlty different but is very similar to the Atmos (with the exception of a thinner waist strap).
Interior space: The Exos does not have a sleeping bag pocket (another way to save weight), so your bag goes right inside. Basic math says the Exos 58 should be 7 liters smaller than the Atmos 65, but in all honesty unless you are packed to the brim, there is plenty of space in the Exos. Here's what fits inside: Atom 40 degree sleeping bag, Neoair pad, Fly Creek UL2 tent (with the poles, all inside the pack), Snowpeak 1400 cookset (w/ gas and stove nested inside), my "emergency" stuff sack with meds etc, extra fleece, rain gear, 2 days food and a nalgene. With all this, there was still PLENTY of room to spare. I would estimate that I had the pack 70% full. If you were going winter camping and/or needed a bear canister or something, this pack would be fine.
Other features: like other reviews said, it would be nice if the gear straps on the bottom clipped on an off. I tested it and the Fly Creek fits in the allotted space with ease, as most smaller tents would I would think. Water storage is typical to other Osprey packs, as is the stretch pocket on the front. There are 2 front zip pockets which are nice for easy access.
All in all, the Exos is a stripped down version of the Atmos, but I'm glad I switched. The bag is durable, light, of Osprey quality, and while its appearance may be a bit misleading, this bag is tougher than it appears.
I bought this pack because it is very lightweight, but I didn't anticipate a problem with the shoulder straps. They are sewn in to the pack and are NOT ADJUSTABLE! I am 5'11" and typically take medium sized things (such as this pack), but I was NOT able to get the weight off of my shoulders and onto my waist. I am a backpacking guide for my university and know how to fit/adjust backpacks and still had a problem.
That being said, this pack's design (aside from the shoulder strap not being adjustable) is great. The ample ventilation in the back is amazing and the pack is UBER lightweight! It is the 3rd Osprey pack that I have owned. I will be returning it, but will probably replace it with another Osprey.
Now Osprey is a tried and true, trusted brand and I got a lot of respect for their products. I truly admire how they were able to jam in so many convenience features while keeping the weight at a minimum. One feature I'm quite enamored with is stow-on-the-go trekking pole attachment that works quite well. Its lid and small compartments in addition to its main packbag are all great conveniences that I appreciate. The issue for me ended up being its suspension, which to me is the most important factor in procuring a backpack. The mesh back panel of its modified airspeed suspension is very comfortable and it should conform to all types of body types; however, in an effort to facilitate ventilation, the main body is separated a bit from that same back panel, pulling the bulk of the weight away from your back. I felt a quite a bit of weight swing as I rotated about my hips. I like the weight to stay as close to my body as possible, and the bag was not doing it for me. For reference, I'm 5'11" (21.5" torso, a bit long for my overall height), 170 to 175 lbs, and 31" waist. However, it doesn't mean this bag won't be a gem for you.
I wanted to like the pack but I have a few complaints which probably do not reflect on the quality of the pack and instead my needs. I would regularly find myself filling the pack entirely on trips and the loads seemed to focus their burden on smaller surfaces probably due to the smaller, lighter materials and straps used to keep the pack weight down. Also when the packs fully loaded I would find the sewn seams pulling away form each other which started to happen after relatively few uses. The number of pockets and their location is amazing, there is a spot for everything. I ended up returning and purchasing the Atmos 65 which will hopefully address the comfort with larger loads and durability issue. Love Osprey!
