Unanswered Question

If the pack is purchased second-hand (used), will the hip-belt "re-mold" to the new hip-dimensions of the second owner? Thanx

Unanswered Question

Any women out there with this pack? What do you think of it? Know that Osprey runs a "Xena" pack and not quite sure what the differences are other than that this one is $40 cheaper, slightly lighter, and has better reviews. Not sure how "mens" packs differ from "womens," but none of them fit very well on a short person with giant hips and a giant bust. Sternum straps and DD's are seemingly non-compatible.

Great Tree Climbing Pack ;)

Great Tree Climbing Pack ;)

I couldn't resist climbing up this old growth douglas fir tree. Even with 60 pounds on my back it was surprisingly easy.

After a couple uses, the Aether fits, and snugs right out to my back, so well that it really feels like a part of me. This makes for great balance on narrow trails and cliffs, and on icy patches of snow.

...or when climbing trees. lol

Excellent pack, well built, comfortable

My initial use of this pack was a 30 mile three night trip. I had 60 lbs in it, and the moldable hip belt was stock (not custom fit). I had previous problems with the hip belt on a lighter Osprey pack (see my review of the Volt 75) and this one dramatic improvement! The first two days was ok, but my hips were getting sore and i wasn't looking forward to day three, but to my surprise day three felt better! The hip belt settled in and I was able to tighten in more each day until it didn't chafe at all.

It's very well build, heavy duty construction, and handled the eight well, with plenty of volume to spare as well. I like the openings on it, and the top lid has a lot of volume which I like for storing often accessed items. The compression straps work well to suck things up close to your back-it feels solid and well behaved.

I expect to have this pack a long time!

Backpack in comfort.

  • Familiarity: I've used it several times

I recently took this pack for a 10 mile, 5000 vertical foot gained, trek into the alpine region of the Wasatch Range. It outperformed not only my expectations, but disjointed my reality that a pack could feel so comfortable and mobile with weight while ascending vert!

The sizing is crucial of course, but I found this pack's moldable hipbelt allows for pretty much all of the weight to sit centered on my hips and relieves all tension from my shoulders and back. This allowed me to hike uphill for an extended time and pace without discomfort with the weight distributed squarely.

The pockets and features are similar to other packs but everyone should rely on their own personal use for pockets etc. The compression system on this pack allows it to be tension-ed down into a sleek and mobile pack.

I haven't the chance to obliterate this thing yet but i expect it to hold up to the strict abuse.

Love It, My go to

  • Familiarity: I've put it through the wringer

This is the backpack I use on my larger backpacking trips in places like Alaska and the Tetons. I have an older model but it has withstood the test of time. The clean look is nice because it keeps all the gear nice and centered on your back. even with the clean look, there are a multitude of straps to get your sleeping pad, tent and gear that needs to dry on there with no problem. I especially like the mesh/stretchy pocket on the outside because it is perfect for accessing rain gear without having to open any pockets or undo any buckles. Also, the top comes off as a fanny pack for day excursions on longer trips. Lastly, the addOn system (just a series of cord loops running vertically along the back) made it easy to add an Osprey Daylite while gearing for a 28 day expedition in the Wind River range this summer so I did not have to buy a new pack. All in all, if I had to buy a large pack again, it would be this one hands down.

Amazing pack

  • Familiarity: I've put it through the wringer

This pack is amazing and can fit everything you may need for multiple nights. I have recommended this pack to several friends and they all also love it. If you new or looking to upgrade this is the pack for you

How's the fit? I am stocky guy with large torso. I am 5'11", weight 205 lbs, have a 44" back and a 36" waist. My torso length is 22". According to the sizing guide I should go with a XL but those sizing guides are a hit or miss kinda thing.

Best Answer Responded on

It does have an adjustable torso, but I would highly recommend you find a store that carries this pack and try it on. I am boarder line medium and large and I went with the medium and with the adjustable torso I have no issues with it.

Responded on

I'm 6'4" and 260lbs and the large fits me perfectly. So may want to look into the medium.

But as Pat suggested, go to a store. This pack has interchangeable shoulder and hip straps. So your ideal fit may be a large waist and medium shoulders. Let a pro fit you.

Will this pack carry skis\splitboard like the old Argon and Aether pack would?

you could probably hook them up with the different compression straps. It is not specifically designed for them but there are enough straps you could make something work

Great pack

  • Familiarity: I've put it through the wringer

I was on the fence between the Aether and the Baltoro a while back and they were both comfortable so it came down to which had more features I wanted. the Baltoro won back then. When I saw the updated Aether and found it had all the improvements I wanted I jumped on it. I am glad I did I love this pack.

The trekking pole holder is much better than other packs. Being able to put your trekking poles away with out taking the pack off is really nice.

The add-on compatibility is nice too. I got the daylite day pack and it really makes it easy to bring a day pack with you if you are going to do some base camping. This was unheard of and difficult with other packs.

The hydration pouch on the outside is another great feature. It makes it easier to take the reservoir out to refill or use elsewhere. I have noticed that you need to put the reservoir in first to make a little space for it but hey it still works.

the hip belt pockets are great for carrying the items you need at hand. the pockets are bigger than other packs which is really nice.

This is an all around great and comfortable pack. Out of all the packs I have owned over the years this is by far my favorite.

well built

We rent these out at my work, extremely durable pack that will last you a long time. It contains more than enough room for all you personal and camp gear! I typically put my sleeping pad between the brain and the body of the bag and then tighten down to compress. I also use a trash bag, put the trash bag inside the bag then put everything else in there to make sure nothing gets wet, which is a cheap way of doing it but effective. I promise you'll be happy with the Aether 85
