Osprey Aether AG 70 Backpack


Osprey Aether AG 70 backpack described in the text is a part of a new anti-gravity series introduced by Osprey recently. This 70 liters pack is the middle-size in the series which also includes packs of 60 liters and 85 liters. This is the ultimate backpacking tool for extended tours, with many extraordinary features.

Bonuses

  • Top lid converts to a fully functional daypack.
  • Attachment points for the Osprey Daylite pack.
  • Rain cover.

Key benefits

  • Advanced suspension system.
  • Adjustable torso length.
  • Moldable hip belt and harness.
  • Interchangeable hip belt.
  • Interchangeable harness.
  • Four sizes to choose from.

The most important changes introduced in the new AG series

There are essentially two:

  1. The harness is completely redesigned.
  2. The daypack is completely redesigned.

To compare, please see my text about the previous version of the Osprey Aether 70 pack.


Aether AG 70 pack – description

About the sizes first. As you see from its name, the Aether AG 70 is officially a 70-liter pack, but in fact, it comes in four different sizes/volumes. So you have 67, 70, 73, and 76 liters versions to choose in the moment of purchase. Its harness also comes in 4 different sizes, S, M, L, XL, and the same holds for the hip belt. Imagine how many combinations you have to choose for an optimal fit. If this is not enough, the harness is adjustable.

This is a top loading pack with a removable lid and a spindrift collar underneath it, but it has an extra access point on the front. It is J-shaped, the same as in the previous model, so this makes it different from the new AG 60 liters pack where the entrance is on the side.

The bottom compartment is with the standard zippered entrance, and the divider between the main compartment and the bottom section is removable.

The suspension

The new AG suspension is supported by the LightWire tensioned, full peripheral frame. The best part of this construction is top-to-bottom suspended mesh that wraps your back, shoulders, and hips. But this is different from their starting design used in the Atmos and Aura series, although the new tensioned mesh used here looks really cool.

The hip belt ISOFORM 5 CM is interchangeable and with custom heat molding. For molding, you can use an Osprey’s oven, or you can just use the pack for several days and it will mold naturally by your body heat. So no worry about this, you will have a perfect fit in any case.

The ISOFORM 5 AG mesh harness is also interchangeable and you can choose one of four sizes.

So again, the harness and the hip belt have some break-in time and they accommodate and form to your body shape after a few wears, and this is the actual meaning of the word ‘isoform’.

These features are also a bonus because family members or partners can use the same pack, and they can use their own specific molded hip belt and harness.

See here how Osprey’s oven works:

To adjust the harness, slide your hand between the back panel and harness and break the Velcro hook and loop connection. After that move the harness into the desired position and press to re-engage the connection.

The lumbar zone is without the usual padding, just a mesh.

Top lid – convertible to a daypack

In the previous Aether version, the removable lid serves as a lumbar pack for short tours. This is completely changed in the new AG version where you have a fully functional DayLid daypack with 16 liters of volume.

Note, the big pack is equipped with an additional flap with buckles, to use when the lid is removed, so you can close the big pack for protection from elements.

The DayLid daypack is with the following features:

  • Shoulder straps are with mesh and edgeless wrap.
  • You have dual access to its main compartment.
  • It comes with an adjustable chest strap.
  • There is a zippered pocket.
  • It comes with an external hydration sleeve.
  • There is a tuckaway attachment loop on the bottom, which is paired with a bungee cord on the top, to attach an ice axe.
  • There are four attachment webbing loops.

The sternum strap of this DayLid daypack can be fixed to three different positions, there are loops on both shoulder straps for this purpose. The loops that are not used for the sternum strap, can be used as attachment points for other equipment.

So, I will not exaggerate by saying that nothing on the market can come close to this extraordinary design. There are many backpacks with daypacks, but no one can be compared with what you have here.

Pockets

There are seven in total. Dual stretch mesh pockets are on the sides, dual zippered pockets are on the hip belt, there are two zippered pockets on the lid, and you have one large stretch mesh pocket on the front.

Attachment points for Osprey’s Daylite pack

StraightJacket compression system with flaps.
StraightJacket compression system with flaps.

On the front of the pack, there are two vertical flaps and two horizontal straps, see the picture below. This is the part of what they call the StraightJacket compression.

When you undo the horizontal strap, underneath the flaps you will see 4 attachment loops. These are the attachment points for the Osprey Daylite pack, which is designed for such a purpose and it can be added to many of Osprey’s packs.

So this is yet another bonus with the Aether 70 AG pack, though this pack is not an exception, many other Osprey packs have these attachment points, but they do not have the flap system used here.

Other attachment points & straps

I already mentioned the four webbing loops on the lid (they appear as attachment loops on the DayLid daypack). Two attachment loops are on the bottom for ice axes or for trekking poles, and those are paired with bungee cords higher up.

The pack comes with the Stow-on the-Go trekking pole attachment system. This is a nice feature typical for many packs of Osprey, useful to have when you need free hands on the fly, like when you have to scramble, to eat something or to drink, or to take a photo.

Dual compression straps are on the sides, and the lower straps are with InsideOut features. This means that you can route them through the pocket (when you only want to compress pack when not full, to ensure its stability), or you can pass them over the side mesh pockets to secure items stored in them.

There are two removable compression straps on the bottom. As already mentioned, on the front you have the StraightJacket compression straps.


The pack is a bit heavy but see what it offers. The weight is the consequence of many useful features. I have some objections regarding the ventilation and lumbar support and I have discussed this in my text about the Osprey Aether AG 60, so please have a look there.

There is a lot of confusion regarding:

  • The rain cover.
  • The external hydration sleeve.
  • The DayLid day pack.

I have been in touch with Osprey about these issues and all is described in the Aether AG 60 text.

Conclusion, rating, pros & cons

In summary, I do not have much more to say about this Osprey Aether AG 70 backpack, you have seen the facts and features. This is a very sophisticated tool and this is so obvious. The daypack is its true standout feature, no pack on the market can come close to it with respect to this.

Though this new AG series is not perfect and I do have some objections. There are a few missing features, and things which I am not happy with, and I discussed them a lot in my text about the 60 liters version. Note that there is a bigger version, Osprey Aether AG 85 described in the site. Please see below how I rate this Aether AG 70 pack:

You have seen the Gregory Paragon 68 pack in the comparison table above, very lightweight and advanced new design. So, just to know that it also has a daypack converted from the internal sleeve, but it is with fewer features of course.

Also, if this Aether AG 70 is too expensive for you, check the Kelty Coyote 65, this is a new pack in the series. Finally, to stress that there exists a parallel Ariel AG series for women, so please see my text about the Ariel AG 55 and Ariel AG 65.

    Ciao,
    vorrei sapere, quali modelli Osprey tra Aether AG 60 e Aaether AG 70 ha lo zaino dentro il cappuccio?
    grazie

      Hi Marco, the situation is described in my text about Osprey Aether AG 60. I think nothing is changed, so in EU they sell the pack without the daypack, on the US market the lid converts into the DayLid daypack.

      Here is the reply in Italian:

      Salve, la situazione è descritta nel mio testo su Osprey Aether AG 60. Penso che nulla sia cambiato, quindi nell’UE vendono il pacchetto senza lo zainetto, sul mercato statunitense il coperchio si converte nello zaino DayLid.

    Hi Jovo,

    Thanks a lot for great and detailed review of this pack! A very few reviews of this pack are available out there at the moment and none of them are so detailed.

    Have a specific question though. How would you compare this exact pack to the Atmos AG 65? You’re mentioned difference in the the AG systems of both, but it is not very clear which is better and in which sense. My understanding is the Atmos is ventilated better, but the Aether better distributes weight.

    Wondering how would you compare those two?

    Thank you!

      Hi Max, Atmos AG has received so many awards in the past, and Aether AG is yet to prove its quality in practical use. I would not say that Aether distributes weight better, do not see reasons for that; the two packs are very similar in that respect.

      But your question is interesting and perhaps I could even claim that it is the other way around, but I am not sure of course. In my text about Aether AG 60, I mentioned that the modified Sirrus and Stratos series look more anti-gravity than Aether and Ariel AG, in the sense that they more resemble the structure in the original AG design in the Atmos & Aura AG packs.

      You surely have a better ventilation in the Sirrus and Stratos packs, but this is not what you are asking of course.

      In general, with such items it is always about feeling and comfort plus the list of specifications. So Aether AG has more, the DayLid is a great part of it. But the rest is personal, you feel it right for you or not. Compare this with water filters. You get sick after drinking filtered water, or you do not. Then you know which is good, there are measurable criteria for that.

    Jovo,

    Thanks for including the 70 liter version on your site. This is actually the size I’m interested in.

    I’d like to get your input on sizing. I’ve gotten input from a couple other sources, and would like yours as well. My torso length is about 18″, my hips/waste are about 30-31″, and my height is about 5’9″. So it’s seems I’m in-between sizes, and either a small or medium could potentially fit. Do you have any idea of which size would probably be better for me?

    Obviously each person is different and you can only get a general sense of my size/frame from personal measurements I provided, but I thought your perspective and insight might be helpful. Thanks you.

      Hi Alan. It is hard to say when you are in-between sizes. I would go to the nearest shop and try any Osprey’s pack in this category size to see how it fits.

      But let’s think out loud, imagine it is too big or too small. What makes the difference?

      Regarding the harness/torso size, I would go for bigger rather than for smaller; if too small, then you might have less padding in the shoulder zone, (and the waist belt will be sitting too high which I dislike). If too big, you have padding longer around the shoulder so this is not bad, but the waist belt is sitting too low. The shoulder strap padding should be all the way around the shoulder, plus at least 1-1.5 inches; if you have more this is not a problem. But too low positioned belt may make it necessary to move it higher and adjust the shoulder harness which can be done.

      I believe the same reasoning could be applied for the waist size, padding extended farther around the hips is not a problem, better this than not having it enough.

      Yet, since this is in-between size, the differences are not big and bigger would work better. But I am sure you can also have a totally opposite opinion from somebody else.

    • Alan says

      at

      Actually, you’re speculation is consistent with most others I’ve read and heard from. For someone between sizes most recommended going with the larger size. In my case this would be a medium rather than a small.

      As you describe, it’s generally not too difficult to make a make slightly larger than ideal fit a smaller user. But if a backpack is too small it more difficult to make it work. I’ll be going to REI tomorrow to try one out and will compare the small and medium.

      Thanks again.

      Hi Alan, I am just coming from our outdoor shop, I was checking if they have received Aether AG, unfortunately not yet. But related to our conversation here, I was checking with Atmos, so yes I agree with you, I would rather go for a bigger model rather than smaller. Good luck in your search.

    Hi, Daniel
    I live in Norway. Hike in the mountains every day, all year. Weekends, holidays etc with a Hilleberg Nammatj 3, Exped Downmat, Rab Neutrino 600, Primus Omnifuel II together with clothes, food, gas and equipment. Probably need 70-80 liters backpack that carries comfortable 10-20 kg. The Osprey Aether 70 and the Gregory Baltoro 75 looks just right. Aether is lighter but I see you give a higher score to the Baltoro. Please give your detailed information pro/cons for our use og hiking in the mountains by foot 1-10 days. Also in winter with solid mountainskees and needed stuff. And of corse backpacking holidays. Sometimes by bike or kayak.

      Hi Peter, this is Jovo the founder of the site, I assume these questions are for me and not for the visitor Daniel. From what you write I understand you use the pack for multi-day tours, so yes it is ideal for such a purpose.

      As for your questions about my higher rate for the Baltoro pack, this is my personal feeling, I find this pack more sophisticated, one of the best that exist, and it has a rain cover which is a must for me. Aether is a bit lighter but it is also smaller. None of the two packs has attachment elements for skis or snowshoes, so there is no point of discussing these things here, those are just excellent backpacking packs.

      You might want to see the new version of the Aether AG, I have reviewed the 60 liters pack and the review is really thorough. The features of the 70 liters pack (I mean the new AG version) are almost the same. My rating for this modified 60 liters Aether AG pack is higher than for any other pack presented in the site, so the same rating is for the 70 liters pack. Have a look, you will love to see what they have done with this pack. It was great and it much greater now.

    I have to say – that guys beard on the video is impressive! :)… I can see that this backpacks are expensive, but it’s important to have quality, esp if you’re on an extra long hike carrying a heavy load for hours at a time. Ultimately, I think it’s reasonable for the price and is definitely big enough for what I’d need personally! thanks for the info.

      Hi Netp, great to hear from you. You are right, this pack is expensive but this is the top of the top, hard to invent something better. I would not consider cheap things for serious tours, you need reliable stuff out there. All the best to you.

    Hi,

    This is a nice backpack for mountaineers. 2.2 kg is a lot of weight. Please isn’t there any alternative weight of this backpack?

    I think it is a perfect pick for mountaineers looking at it capacity because without 70 liters of volume that is really a lot of space. Please you didn’t outline how it is use.

    Keep up! Cheers,
    Daniel

      Hi Daniel, this backpack is among lighter models, just to know. Bear in mind its size. As for alternative weight I am not sure what you mean, there are other models and other sizes, so the weight depends on the size. Not sure what you mean by how to use. Put on your back, adjust the harness and the belt, and more or less that is it.

    I think that is a pretty nifty backpack honestly! Like you mentioned it would be great for hiking or camping! Now the only thing that kind of shocked me was the price! Although I spend a lot of money on things like clothes, I could exactly figure out what drove the price so high, something I missed?
    Thanks for the review!

      Hi, this is a top quality backpack, the price is in close correspondence with it. When you are on 3000 meters you do not want malfunctioning on your harness or belt. I have my Deuter pack which is the same as it was 12 years earlier when I bought it, and I am an active climber. Similar is with Osprey, you buy a quality tool.
