Rated 4 out of 5 by from Aether - Love this pack Was at REI over this weekend and purchased this pack. Currently using a Kilty 90 Redcloud but it is sized a bit larget so thought I would give this a try. Walked with 40 pounds at Devils Lake for 8 miles and this Aether pack fit like a charm. Loved the way it hip belt felt wrapped around my waste and gave perfect weight distribution. This is my first Osprey pack and I can truly say we are going to be best friends. Only rated a 4 due to lack of exterior pockets. My Kilty has 2 large ones along the sides but this one only has the water bottle holders, stuff sack on front, and 2 additional on top. This is really a 4.9 rating. Feels extremely durable. Took another 4 mile walk today with more added weight and it seemed to feel better today than yesterday. Next up Isle Royale in May. Highly recommend this pack. Also I like the full frontal zipper for access to internal items. Osprey hydration 72 liter was a bonus bit haven't utilized yet nor the internal smaller "Go bag". Thanks REI for talking me into this pack while at the store in Madison.

Rated 5 out of 5 by from It Makes Half Of Your Pack Weight Disappear Tried other packs, even the 2016 version and there's no comparison in comfort. I'm 5'8" with a 17" torso (I had to accept that the S was what I needed mainly due to load lifter fit)) and I'm still playing with the adjustments after a 30lb. day on the trail. It is very fit-sensitive and at one point I could not feel the hipbelt. Lift the pack by the top grab strap and feel how much lighter it seems when it's on your back. Love the zipper pull rings. Hate the tight side pockets (Listen to the crunch of the Smart Water bottle when the pack is full). If not for the mandatory bear canister and Rocky Mountain clothing, I would have gone with the 60 liter. Will use the reservoir in a smaller pack. I use a 3L Camelbak and let the tube hang out of the top. It's just easier that way. Hipbelt pockets are fine as I store lots of small items in them. Four Stars but the comfort makes it Five.

Rated 5 out of 5 by from Best pack I've owned Didn't get a big overview of the pack before I bought it, but when I discovered the top pack turns into a day pack, I was excited. Lots of storage, lots of different access. simply loving it. carry my girlfriend's gear plus my own in here with no trouble.

Rated 5 out of 5 by from 2017 redesign promises improvements over 2015/16s My son and I both purchased the 2017 Aether 70 AG to replace our 2016 and 2015 models. The new 2017 waist belt feels and looks stronger than the 2016 and we like the day pack better than the waist pack of the earlier models. I loaded it up with 40 lbs. in the show room and the Aether felt better than the 2016 model. Planning a trip this summer to see how it performs on the trail.

Rated 5 out of 5 by from Made our trip so enjoyable! So happy I purchased this pack. Worked great and is going to hold up for a long time. I've been using a old external frame for the last 5 years and finally purchased a high quality pack-this is it! Thanks!

Rated 5 out of 5 by from Great weight distribution I have yet to put this pack through a few trips but I have no doubt it will perform better than any pack I've had before. I've fully packed this pack at home and it has plenty of space for everything a hiker would need for a week long trip. What sold me was when I was in REI. The sales associate and I put about 20 lbs in the pack, fit it to me, and I wore it in the store for 15 minutes. While I was wearing the pack I thought "yep, feels like I'm wearing a pack". But once I took the pack off, the pack felt substantially heavier in my arms. Not only does the pack put all the weight on your hips, it can be synched way down for a small weekend trip's worth of gear. Mine came with a hydration bladder, and the awesome day pack. Highly recommend this pack to anybody that's in the market.

Rated 4 out of 5 by from Be aware of the differences to the non-EX-version Getting limited with my old North Face backpack and seeing my brother being very satisfied with his older (non AG) Aether 70, I decided (after having read multiple reviews in magazines and websites) to get myself the new version. I did so a couple of hours before returning to Germany. I really appreciated the employee at the Manhattan Beach Store helping me to pick the right size (torso, belt, ...). The local store informations mentioned that the pack comes in an exclusive coop version, including a hydration reservoir and a top lid convertible into a daypack. "Great!", I thought, "I get some add-ons". Unfortunately, beeing a little bit in a hurry, I did not check the backpack in depth. So that I didn't notice the differences to the "normal" (whose reviews I had read) AG version, which - for me - are a big downer. The coop-exclusive AG version does: - NOT come with an external, but an internal hydration sleeve. So each time I have to (re)fill the bladder, I would have to get it out of the main compartment. Which mostly means taking stuff out of the pack in order to be able to retrieve the bladder, getting it out and filling it, and the get everything back in place. Very annoying. - NOT come with an integrated (but removable) rain cover in the top lid. - come with a top lid that is said to have a capacity of 16 L. Instead of 9 L the regular version is said to have. Both packs beeing 70 L, does this mean, that the EX's main compartment is smaller that the one of the regular pack? There may be more differences I don't know yet, not having the regular version. The EX version sure is a great pack too. But I wanted the regular version and supposed, that the EX version only brings add-ons, but not major differences. For now, I will stick to my old backpack, and return the EX-backpack when I'm getting back to the US next fall.

Rated 5 out of 5 by from Sturdy and well-designed I've had this pack for several years and have taken it all over the place. No pack is perfect, but this comes close. With a 30 lb-plus load, I can wear it for hours, even on steep trails. Belt and straps are comfortable (given that you are lugging things on your back), easy to adjust and don't slip. Nice features like the oversize web pockets, gear straps and removable top. Best of all, it's tough -- so far it shows virtually no signs of wear.

Bought this pack and in the description it states that i has external water reservoir and side zippers. Instead it has internal reservoir and front J style zipper. Did i get sent the wrong pack or the pack was this pack advertised wrong?

Asked by: Trekker5007
This pack has an internal sleeve to hold a water reservoir and external side pockets for water bottles. A large J-zipper is located on the front panel which provides access to the main compartment.

I ordered my bag on Jan 8th and received it today (Feb 2nd). The original description stated it would come with a rain cover. Did this change? And why? It was one of the reasons I ordered this particular bag.

Asked by: RedneckArmyVet
The Osprey Aether 70 AG EX does not include a rain cover. Instead, Osprey has included a reservoir with this pack. Please contact us at (800) 426-4840 to discuss your order.

How can I go about ordering a small torso size with a medium hip belt? Do I need to go into a store or can it be done all online?

Asked by: Mountain Kewina
In the case of this pack, we recommend ordering a size small. In addition to the pack you can order the medium Osprey IsoForm5 CM Custom Moldable Hipbelt. https://www.rei.com/product/111305/osprey-isoform5-cm-custom-moldable-hipbelt-mens Once you receive both items, you can swap out the hipbelts and return the small belt to the store for a refund.
