Conquering steep rocky pitches on day two of your solo-backpacking trip into the Cascades might be daunting to some, but with your know-how, strength, and Osprey Aether Pro 70 Backpack you feel downright unstoppable. This pack falls as far into the "featherweight" category as a 70-liter can, weighing in under 4lbs (size medium), so you can pack in all of your necessities without being weighed down. It features the newly reworked back panel and Lightwire Suspension system that makes heavy loads feel more manageable while you dive deeper into the backcountry by using a lightweight aluminum frame to transfer your load to your hip belt, alleviating pressure on your shoulders and back while you pick your way through overgrown trails to the next valley where you'll spend the night.
To make sure you're fully prepared for whatever adventure you choose, the pack is equipped with ample straps for carrying sleeping pads, trekking poles, and ice tools, so you're not limited with your choices. An internal pocket offers space to add up to a 3-liter reservoir for added hydration, and pockets at the hip belt give you quick access to your maps and snacks. On back you can add an additional Osprey Daylite pack or Alpine Pocket, so you can go for quick out-and-back day hikes once you've set up your base camp, without the need for lugging your whole pack along on the trip. If you're going for streamlined, the Aether has the answer for you with a removable top lid, removable ice tool loops, removable side compression straps, and removable sleeping pad straps, so you can shed weight as needed, while still carrying the gear you need for an overnighter or weekend expedition.

This is for serious hikers
[This review was collected as part of a promotion.] This is for serious hikers who want a pack that is as light and strong as possible. No bulky side pockets and endless zippers, which makes it a narrower and great for brush heavy trails and, I suspect, mountaineering. It has an adjustable torso length, like many Osprey models and is super comfortable! We have three similar sized Osprey’s of different models and this is by far my favorite for any long distance trek.

Osprey Aether 70 pro review: almost perfect
This is almost the perfect large (>50L) pack. Before purchasing this pack, I read all the reviews I could find since it was relatively new at the time. Most of negative comments in the reviews were nitpicks and didn’t turn out to be a bug at all but actually a feature. For example, several people commented on how they wanted extra pockets, but this pack is designed for extended mountaineering/trekking trips, so it prioritizes simplicity and comfortable load hauling. There were other comments about the pack being too narrow, but again this is what you want for a climbing trip. You want the weight to be close to your body. There are plenty of other packs out there that have more pockets and more features, etc. Anyways, only one of the comments ended up being a big issue: it’s not helmet compatible. This is a big swing and a miss for a pack targeted towards mountaineering and is the only flaw I can find. However I think it is a big design flaw and hence why I gave this pack a 4 star review. I’ve seen pictures of sherpas in the Himalayas wearing this pack with the load lifters all the way loosened. I didn’t understand why they did that at first, but then I noticed they were wearing climbing helmets and the only way they could look up with a climbing helmet on was to loosen the load lifters all the way. Osprey–please do a slight redesign of this pack and make it more helmet friendly. This could be achieved by changing the frame so that it does not need to curve in so much. I understand that a frame that curves in will keep the weight closer to your center of gravity, but considering the use case of this pack, I think that helmet use should be prioritized. At the very least make a little cut out like the Gregory Denali pack has so that you can look up with a helmet on. It almost becomes a safety issue… climbers and mountaineers need to be able to see what’s ahead of them, and often times this is in the vertical direction not horizontal. When I wear this pack with a climbing helmet, I cannot tilt my head up at all, I can only look straight ahead, which is not ideal when climbing. Other than that one flaw, the pack is pretty much perfect. All of the features are minimal yet effective and can be stripped down to shed weight. The zippered hip belt pouch is the biggest I’ve ever seen on a pack and can easily fit a whole lunch or snacks plus other items that you may want to get out quickly like a compass/map/GPS. I love how big the zippered pouch is and wish this size was used more often on other packs. The other hip belt pouch is great too. It can hold loose items, but it’s better for a water bottle. I like the shape of it because for winter mountaineering, it will fit a Nalgene that is inside of an insulated bottle parka. I think Osprey is onto something with these removable pouches on the sides of the pack which offers customizability and versatility–pack designers should consider this idea for future packs! Some people think the stow on the go trekking pile is gimmicky but I actually make use of it. I’m all about features that don’t make you have to stop and take off your pack. So those 4 things (water, food, navigation, storing trekking poles) which I often need access to on trail are easily in reach without taking off this pack. There are also plenty of straps and attachment points on the pack, but not too many. This was a smart move since Osprey is known to make packs that are too “over-engineered” by the mountaineering community. Not with this pack! Again, I see a lot of complaints about not having enough features in the reviews… buy a different pack! This pack is designed to minimal, somewhat lightweight, but still be able to carry a ton of gear (I’ve carried 50 pounds in this pack for a training hike and it carried it like a champ, didn’t seem bogged down at all)– they really hit the sweet spot which I have not been able to find with any other pack on the market. Amazingly, it offer all of this at a reasonable 4 pounds pack weight. And if that isn’t enough, I think this pack is more comfortable and carries weight better than the regular Atmos and Aether series of packs which I’ve owned in the past. I think this is partly because the hip belt and shoulder straps are a little firmer than the other Osprey backpacking packs. I think the foam/padding in these other Osprey packs is too soft and doesn’t support loads over longer periods of time as well as the Aether Pro 70. One other minor quibble is that the ice tool/glacier axe attachments aren’t great (especially when compared to the Mutant series packs… those have the best axe attachment points I’ve ever seen). I had to adjust the loop at the bottom of the pack so that it fit my ice tools better. Then at the top of the pack you just have to use the compression straps to keep the tools from moving… not ideal. I don’t know why they couldn’t add two small shock cord tie offs like on the mutant packs to prevent the tool shafts from moving at the top. I also wish they had 2 rows of daisy chain that went along either side of the back of the pack (again similar to the Mutant series of packs). I like to use voile straps to attach my crampons to the back of the pack on daisy chain (which I personally think is one of the better ways to carry crampons). There are 2 sewn loops of grey cord (hard to see in the pictures) that I’ve been able to use for this, but it wouldn’t add much more weight to just sew on daisy chain instead. TL;DR this is by far my favorite pack above 50L for extended treks/mountain objectives. I’d give it a 5/5 if it was helmet compatible, but I have to subtract a point for that major oversight (but only because it is marketed towards mountaineering… this would not be an issue if it was marketed exclusively to backpackers). The other nitpicks I mention are all minor details that don’t necessarily detract from the pack but are just personal preferences. Essentially I wish they took a few more design ideas from the Mutant series and incorporated them in the Aether Pro 70. Anyways, I rarely write reviews, so great work Osprey making a pack that is rad enough to inspire me to jot down some thoughts!

A great deal of top sway-even with nothing in lid!
I really had my heart set on making this pack my alpine mountaineer pack! Just like my zenth 88,varent 52,37 and 34 climbing packs! I sure was surprised after going on a overnight test-trip how many things were wrong with this pack! No matter what I did I experienced a great deal of top-sway! Hitting my head on the pack whenever I looked up! A very uncomfortable hipbelt! And ONLY ONE water bottle pocket? A lot of money for what?

Really Impressed
Really impressed with comfort carrying up to 15kgs on trails that require bush bashing, minimal snagging due to narrow, taller profile (with 'brain' removed) No secret that it's not an ultra light player but suits my desire to balance comfort with overall carry weight. One suggestion to Osprey is to add a lower finger catch on the main shoulder buckle release. Having a more accessible mini lever to release when fingers are cold or wearing gloves would make big difference. Maybe a re- think on moving hip belt pockets further to from for easier access? I love the trekking pole shoulder strap loop and hip belt anchor point. Only takes one 'pole jiggle' to figure you need to double loop the shock chord around pole handles. Really good side and outer sinch straps to keep things sleek and compact. As Osprey (or someone:-) ) describes 'mountaineering/trekking hybrid that delivers comfort and performance for those seeking a key equipment partner to explore beyond the more travelled routes.

Almost perfect. Love the simplicity. Bad for climbing.
I love how simple the pack is and yet how comfortably it can carry heavy loads. It is quite narrow and tall, which took some getting used to but now that I have it figured out my gear will ""tetris"" in nicely. Perfect balance of lightweight yet durable, and adding a daylite is a good option. Not sure I'm buying the 70L but maybe that's just because it's narrow. If I could make changes it would be these: 1. one more small zippered pocket in the brain for rarely accessed things like keys. 2. Bend the upper area of the stays back just an inch or two so there is some clearance for your head. I tried a 3rd class scramble and I will never do that again, the pack blocks your head from looking upward. Downright dangerous. Not sure how a pack designed with Nimsdai Purja would overlook this but as it is I cannot use this for 3rd class or above. Especially slabs. Even some 2nd class this pack was annoying. Easier the more vert the route is for sure. In any case it's a shame since it's so light it would be a great dual-use pack for base camp backpacking summit bids.

3 years of use
3 seasons of use, hold up perfectly well. A strip-down \ less featured pack and it works perfectly. All the extra features that I thought would be nice to have from fully featured Aether are not needed. The removable lid makes a nice daypack when you are able to leave your gear at the campground. All the attachment points for outside mounting gear are extremely durable. The things to consider... 1. One of the hip pockets is not zippered, I did drop things out of it a few times bending and now use it for water bottles mainly (because mesh side pockets do no exist on this pack) so you have only one quick access secure hip pocket ( but do you really need more? ). 2. You can only load and unload from the top, sometimes I see people unpacking through the middle of the pack by unzippering the entire front panel and it makes me want to have one... but other than ""want"" there is really no need for it. 3. Same goes for the separate zippered bottom section that is usually separated from the main compartment... seems like nice to have but in reality, the lack of one allows to use more space inside more efficiently.. 4. The only thing I think I miss is shove-it pocket on the outside, the straps allow me to secure whatever I need on outside, but shove-it pocket is just 10times faster and easier to use. Overall I would choose this one over regular Aether. Weight savings didn't compromise this pack's durability, I feel like after 3 years of use I still have another 7 for sure. Worst case scenario - I am betting on Osprey's warranty.

Do not buy this
This pack is garbage. It is a 70 liter bag but can't fit my gear from a zpacks 50 liter arc air. Where did the 20 extra liters go? The design is terrible, only one water bottle pocket and it only holds a nalgene. I want my money back, I feel robbed and mislead with false advertising.

More of a 55+15L pack than a 70L
Took this on a 5day climb of Mt Baker. The narrow profile made it difficult to fit everything, while others in the group were able to fit more in similar sized packs. The top of the pack sits way too close to the head, preventing looking up while going up hill, and completely preventing wearing a helmet (fortunately I had a day pack for summit). There are clips on the hip belt that don't reach if you try and raise the belt. Ultimately, its a fine backpack if not loaded all the way to the top. Good for a moderately loaded 1-3day trip. I'd classify this more as a 55L pack that can carry 70L if you are lazy about repacking on your final leg

Solid and simple
I use this pack for backpacking, alpine climbing, and remote paleontology fieldwork. I appreciate the lightweight and lack of extra pockets for me to misplace things in. As with all osprey packs, it carries very well! I like that it puts loads as close to my body as possible without extra airspace behind the back. My only complaint is the durability of the hip zipper- I work in dusty environments and it got sticky quickly! However, the water bottle holder is the best I've ever had!

Awesome pack for guides, anyone that needs lot of gear.
Bought this pack for a job guiding trips around NW AR, and NE OK. Through 6 weeks of nonstop hiking, plenty of surprise thunderstorms, and battling the crazy OK summer heat, The Aether Pro 70 did a fantastic job. An Average pack weight of 40+ Lbs (more emergency gear than personal gear), and this pack has no signs of giving up, and after a week or so, I did not feel the pack on my body. This pack hugs and fits so well, I truly became one with my gear. The simplicity is what drew me to this pack. I'm not a fan of the packs with wild numbers of secret pockets and flaps, so the simplicity of the Aether Pro 70 was one of my favorite attributes. The large hip belt pockets were one of my favorite attributes, however. I am 6'2"", with a waist around 33"". I bought a Large pack, but had to trade hip belts with my brother, who had a pre AG Aether 65 Medium pack but needed a Large hip belt. So in the end it worked perfectly, with the Large pack and Medium hip belt.
