I've used it once or twice and have initial impressions

This backpack is beautiful, but it was too much for me. It felt sloppy and cumbersome. I would prefer some outside pockets for little things.

Happy with my first backpack

Now that I’ve used this bag on multiple trips and broken it in I feel ready to review. It’s mostly been used on 3-day winter snow camping excursions, and a bit in the summer as well. What I love: the anti-gravity suspension, zipper placement, ease of packing & retrieving packed items. What I thought I’d love and now realize I didn’t need: the top flap that turns into a removable day-pack. Being my first ‘big-boy’ pack, I thought this would be fantastic for excursions from camp, now it just feels like added bulk and a bit cumbersome. What I dislike: no built-in rain fly. And if you haven’t stretched that morning, it can be difficult to reach any side-mounted water bottle. Overall: very happy with this pack. It’s built tough and feels light on your back.

high tech bag

This bag has many conveniences. The pockets are huge, and it is really well designed for easy access to every area. The anti-gravity system is awesome!

not a fan of the suspension system

I returned this product before using it

This is a very well built and well featured pack. I especially liked the huge pockets on the belt. I hike with my family and it is convenient to have lots of snacks and stuff available without having to take off the pack. My one complaint is a serious one however. This pack has a mesh suspension system that holds the pack away from your pack. While airy and pleasant feeling, it also introduces about a 2 inch gap between your back and the pack itself. This results in the weight being carried farther away from your torso. As a result, I found the that even when carefully loaded, the weight is not well transferred to the hips and you get pulled backwards by the shoulder straps. No amount of adjusting was able to fix this problem for me. I had the same problem with the Osprey Atmos which similarly suspends the pack far from your back. I found the Osprey Kestrel, which has a traditional back, does a better job of transferring load to one's hips, despite being rated for lighter loads. My recommendation: if you're planning on carrying a lot of weight and hip loaded weight distribution is very important to you, then leave the tags on, load test this pack at home and decide whether you want to return it before heading into the wilderness.

Thank you for the feedback, Paul. It is important to note, however, that even with packs that have contact against your back, the weight is still a good inch or more away, when you consider all of the foam, stiffeners, etc that are build into a pack design without ventilation. Trade offs, I guess! Definitely a personal preference. Thank you for taking the time to write! Leta Osprey Rep

Thanks for your review. I have been using a Kestrel 48 for a number of years and have been tempted to get an Osprey with the AG system. I have heard mixed reviews. Your review explained one of my concerns that most people don't articulate. Many have complained about hip belt comfort issues. 60l is a large pack that would temp me to carry more than needed. This spring I did 2 different four night five day trips and did not need a larger pack. Your review saved me from hitting the add to cart and purchase. Thanks

Anti Gravity that works!

I've put it through the wringer

As any great adventure, this pack takes a little investment of time to get it right. When I first tried it on all my weight had to go forward to regain my center of gravity and feel balanced. I almost went with something different but fortunately I was determined to take advantage of the new AG. Once I had the harness adjusted properly for my torso and the shoulder straps/load lifters dialed in....WOW! This thing is a BEAST. The compression straps are all in the right spots, the features abound and the water bottle pockets work much better than other reviews lead me to believe. The AG system works amazingly well and for me personally I was willing to give up a pinch of breatheability for the added comfort and support off my back, neck and shoulders. One other small compromise was about 1lb of weight compared to similar packs in the same class. I have been hiking & Backpacking for 20 years and this setup has changed the game for me. I was able to extend my days at Yosemite by hours as well as adding many miles on top of my previous limits and still had energy left and felt less pain the next morning. Honestly carries like a dream, my 50 +/- lb load felt like 35-40. The way the pack 'hugs' your back genuinely kept me feeling much more confident scrambling as well as on steep descents as there is much less weight shift or bounce. I would say con-ish would be the weight (acceptable to me for the features, comfort and support) Could breathe a hair better (also forgiven for the above mentioned benefits and pack durability) Slight tweak to the hydration reservoir sleeve so that the pack retains more air circulation when 2+ L reservoir is full and installed last but not least, Include a rain cover please! There are so many small details that make this pack great, the way the zippers are tucked under the protective overhanging packcloth, adjustable sleeping bag divider, ability to have lower reverse straight jacket compression straps inside or out. A+ Love it!

Great Tech, But Not For Me

So I got to use this pack on a small backpacking trip the other week. Nothing too crazy, just short 6 mile-er into the Uintas. So, a little about me. I was born tall, and have a history of bad hips. I promise this is relevant, give me a second. So, the AG (or Anti-Gravity) system on this pack is a mesh system that is made to take a lot of the weight off your shoulders and put it on your hips. This is generally pretty awesome, as shoulders typically take the brunt of all the weight of the pack. However, because of my bad hips, this was reaaally not comfortable. After a while, my hips actually started hurting, which is not preferred, especially since it was shorter distance. Don't get me wrong, I want to love this pack so much; the quality of the pack is amazing, the pockets are huge and well thought out, and the tech in it is actually really rad. But if you are someone like me who's hips aren't the best, definitely steer clear.

Durable and Reliable!!!

I've put it through the wringer

I bought one of these packs for a 3 month backpacking trip through southern Utah. Needless to say this bag has gone through a lot, and has stood the test the time. I am very happy with how the bag has held up, it is super tough and still works like a charm after almost 7 month of having it. I highly recommend!!!!

Over 1000 miles and still going strong.

I've put it through the wringer

Brief: From overnight trips to long distance thru-hiking, this pack brings with it the comfort and versatility that very few packs in this range can offer. From tramping through rainforests in New Zealand to the Alpine regions of Colorado, I've had this pack in all types of weather with no problems to speak of. While partners of mine were complaining about sore shoulders/back, I was able to trudge on comfortably without any issues. The pack form fits perfectly to the contours of my back - and at 60L with plenty of pockets and space - it's a great size for anyone from those who want to pack lightly to those who want to run a heavier load for a comfort trip (there's even a front pocket that's perfectly sized for my Frisbee)! Of the other packs I've owned (REI flash 62L and a Gregory 50L) this has been my favorite in terms of comfort and durability.

Blake, thank you so much for this stellar review! So glad that the Aether is treating you so well! Enjoy, Leta Osprey Rep

Love all the updates!

I've put it through the wringer

It was easy to choose another Aether after my last one stayed strong for over a decade of multiple, week-long trips every season. It seems like the pocket configuration is more-or-less the same, because why mess with a solid design? The mesh padding on the hips and shoulders certainly feel more breathable and plush, and the wire frame feels sturdier and lighter.

Hey Derek, thank you for your review on the Aether 60. Osprey did a great job with the updates for sure. I appreciate your feedback! Leta Osprey Rep

It was time for an upgrade on the old Aether, there was no question I was going to buy another one.

Osprey Packs Aether AG 60L Backpack

I've put it through the wringer

This is my go to pack! For real this thing is legit. I've been on several backpacking trips with it. 60L forces you to pack smart but I've had the thing maxed out for every trip but Osprey's Anti Gravity suspension system distributes the weight so efficiently, It honestly feels like a day pack, so you'll stay light on your feet. I could go on forever about this pack. Extremely comfortable, customizable, and there's tons of handy features. The top lid converts to a day pack, which is super useful once you've reached your base camp. Any questions feel free to reach out!

Luke, many thanks for a great review. Happy Trails! Leta Osprey Rep

Best friend on your back

I've put it through the wringer

This backpack has been my travel buddy all over the world. Across the Nepali Himalayas, all through Patagonia, the jungles of Thailand and countless backpacking adventures state side. It is as comfortable walking around cities as it is in the woods. The 60L keeps you honest about your packing, just enough for a 4-5 day backpacking trip or a few months traveling. This keeps you from overloading your pack, be deliberate about gear and it should all fit. I am 5'8" and the medium fits well. The shoulder straps are vertically adjustable so you are able to customize the fit. The hip belts also molded well and stay in place while walking around all day. Over the years I acquired a few holes and broken buckles, as expected for hard use. I sent it back to Osprey and they patched everything up like new.

Great review - Zach! Thank you and I am sorry for my late reply! Leta Osprey Rep

Backcountry Comfort

I've put it through the wringer

I love this pack. The Anti Gravity suspension system has to be the most comfortable I've used. I sweat a lot and with this system, the pack is lifted off my back to allow air to flow through and help regulate temperature where the pack would otherwise rest and heat further. I've used this pack for numerous activities, including backpacking, ski touring and some mountaineering objectives. The top lid unclips and turns into a great summit pack that is hydration compatible and even has an ice axe loop too. This pack is not the lightest, but I would argue it is the most comfortable, so if that is what you're looking for, then I would strongly recommend this pack. Feel free to reach out to me with any sizing questions, or any questions about this pack or anything else.


Top lid as a daypack is amazing!

The top lid detaches as a daypack/summit pack and is an invaluable feature of the Aether. The Ariel is the womens version of this bag. Photo from a 16 mile dayhike in Havasupai along the Havasu Creek to the confluence of the Colorado River.


Osprey Aether AG Product Tour

Check out all of the great features of the new Osprey Aether AG series! Leta Osprey Rep


Your description is wrong the hydration sleeve is internal dont feel bad one of ospreys videos says its external as well


Under tech specs, you list this as a top load only pack, but Osprey claims "side panel zip access to main compartment." Can someone clarify?

The Aether AG 60 and Ariel AG 55, (women's equivalent) have a side zip access on the wearers left side panel. This is a new feature to the smaller volumes of the Aether and Ariel AG series for this season!

Thanks for the question, Tyler! Osprey is correct, and this Aether 60 also has a side zip access, as Michale refers to below. I will make make sure to help Backcountry get the specs updated. Thank you for the question! Leta Osprey Rep
