Great mid-size backpacking pack

Rating:*****

The Aether 70 is a great all around pack. I am just getting in to backpacking and spent a long time researching and trying on different packs (all said and done - about a year). I wasn't real sure what I needed, but after my investigation I went with this one. It is a comfortable and fairly roomy pack.

So far I have taken it with me on a 3-day trip in WV over very rugged terrain with around a 50lb load. The pack held up great. I was never unable to get the pack to a comfortable position. By adjusting the straps every now and then I was always able to get it comfortable.

I was lacking in the gear department on my trip so I used what I had - a crappy sleeping bag and tent specifically. I packed in a blanket for extra insulation (hey, it was a cold trip!). Because of that I definitely had "too much" gear. My tent, tarp, and pad were strapped to the outside, as was my jacket for the most part while we were on the move. The straps on the bottom and head pocket on the pack made it real easy to strap on what didn't fit inside. The pack still maintained it's comfort and balance very well.

The back panel is supposed to let air flow better around your back. It is much better than having the typical pad type back panel, however I found it to not cool very well. I worked up a good sweat hiking in a T shirt in 40deg temps. I would not consider this to be a drawback, just a heads-up to those expecting it to be an air conditioner.

I found the internal water pouch pocket to not be that useful. By putting my Camelbak in there I would have decreased the capacity in the main compartment and everything would push up against the Camelbak, pressurizing it quite nicely. I just put mine in the kangaroo pouch on the back of the pack instead.

One thing I will note, and a suggestion I will make, is I have the Argon hip belt and shoulder harness for mine also. These make a big difference to me. The extra padding makes heavier loads more comfortable. I will caution, though, that swapping out the harness/belt doesn't increase the load capacity of the pack as a whole. The suspension was designed to hold only a certain amount (as per Osprey's site it shows 50-65lbs as being OK). If you are in that weight range the Argon stuff will make a difference.

I stopped using suitcases/duffel bags when traveling. Now I just use my Aether 70!

For the majority of backpackers this pack will be a great choice. It fits real well, is balanced and comfortable when carrying decent loads, is a good price, and is very versatile.

Great Pack

Rating:****
Shopped around for just the right pack to take to Philmont this June. I'm a 42 year old man that is going to have to keep up with nine boys on the trail.

Even thought I've done some hiking on the AT in Georgia I know 12 days on the trail will be rough.

For the past ten years I've carried a MS Frostfire 5300 on extended hikes. Very outdated and heavy but one tough pack!

After reading all 59 reviews on this pack I decided to get one for myself and try it on our shakedown hikes. First one was a fourteen miler with a lot of hills.

I have to say most of what has been said about this pack is dead on true.

It pack good and I was able to secure the load easy enough.

The adjustable sleeping bag compartment made it easy to stow my rain suit, Osprey rain cover, Pillow, and sleeping bag for easy access.

The removable lid is very handy in bringing your smaller items into the tent or fire side. Wish it had a internal zipper pocket to help organize some smaller items, like car keys and headlamp, and hygene items.

The hip belt and shoulder straps are great! Very easy to adjust and sintch the load down to your body. Absolutely NO weight on my shoulders!

Eventhough this pack has a nice internal hydration sleve I don't use it for that. I use the outside pocket located on the back of the pack. You can slip a Camalbak hook inside the fabric for the female clip. This way you have easy access to your water when you get to camp or filter refills. The tube is a little shorter in the front, but is an easy compromise for ease of access.

We had a boy twist his ankle on the fourteen miler and I had to carry my pack on my chest, and his on my back for about 1/4 mile as we bushwhacked to a road for egress of the injured boy. I was able to strap the lid to the back of the pack and secure the sterum strap and hip belt to my back and waist. I moved easy enough. Coming back to the rest of the troop I had just my pack as we bush whacked back. That was easy with the load secured to my back. Did better then my Mt. Smith would have done.

My cons are the same as the ones I read, external pockets,access other then top, and hip belt stowage pouches.

Overall I think the reviews here really help me find a pack that is going to work great for Philmont.

Solid, solid, solid

Rating:****
After reading countless positive reviews on this board, I decided to try this pack out. This is my first multi-day pack, and I wanted something that would last me for several years to come. I think I found it! So far, I've used this primarily on a trip to Yosemite earlier this year. I lived out of this pack for 5 days, and while it was packed very tight, I had room for everything I needed. My main concern was having ample room for my large Garcia bear vault, required for all backpackers in Yosemite. Naturally, the vault took up a fair amount of space in the pack, but I was impressed that I was still able to fit everything else in there. When packed right, I had a solid, balanced pack that was a joy to wear considering the weight (about 45lbs.) For flying to CA, I got the REI travel duffel, which I highly recommend for this pack. It folds into itself for unbelievably easy storage when you arrive.

You can tell right away that this thing is very solidly built. After a week of on-trail use, it still looked like new. One thing I appreciate is the functionality of the external straps. They are plenty long enough to strap an empty daypack and boots onto, and the pack was designed well enough that I didn't feel like I would tip over with the added weight strapped on. I LOVED the comfort and airflow that the back padding provided. Sure, you'll still end up with a wet shirt on hot days, but this design at least help to keep that at a minimum.

The only thing I would change is the addition of more external pockets. Several times on the trail I had second thoughts about stopping to get a snack out simply because it was a hassle to take the pack off to get to anything. I also noticed that when the pack is very full, the top zipper is nearly useless, but that's probably my own fault. Refilling the bladder basically requires you to empty over half of the pack - not a huge issue if you store your gear in a couple stuff sacks.

Sure there are better packs out there, but if you find this one on sale like I did, it's certainly a great decision! Now let's see how it holds up for a winter excursion...

A pack for the picky

Rating:*****

The Osprey Aether 70 (my wife has the Ariel 65) is a comfortable pack. The IsoForm Custom Molding hip belt is superb and adjusts easily. Simply pull the strap on each side of the belt to quickly and efficiently adjust it. (We did not find it necessary to heat mold the belt. I've talked to a number of people about this; most do not have their belt heat molded. Apparently, the belt will, with time, mold itself to you waist.) The shoulder straps also adjust easily and make a custom fit a snap, especially the ones at the top. We carried these packs fully loaded up steep trails to almost 10,000 feet with relative ease. There's lots of room. I'm not a big fan (or wasn't at first) of top-loading-only packs. However, if you pack carefully and with a plan, top-loading-only packs work well. I wouldn't complain about a zipper down the left or right side of the main compartment, nor would I gripe about the addition of a few outside-access pockets (for a stove, fuel bottle, etc.). There are, of course, stretch pockets on each side of the pack, which are convenient and work especially well for Nalgene bottles. The top bag is hyped as a detachable fanny pack. I'm not convinced of its usefulness as a fanny pack--at least not yet. It's kind of a pain to detach. However, it is a great pocket as part of the pack and integrates well as part of the overall design. As with most Osprey packs, there is a plethora of compression straps and more straps. At first I thought that this was a bit too much; however, as I get to know the pack better (How do you do? What can you do for me?) and work with the various features, it all makes sense--every last strap and pull has a purpose and does its job well. The packs appear to be well-made to high standards of quality and attention to detail is obvious. A few brighter colors would be a nice addition to the existing colors. I chose sunburst and my wife chose guava. Overall, we are very pleased with our Osprey Aether and Ariel packs.

Excellent versatile pack

The first pack I ordered had a flaw with a suspension strut. This store had a replacement backpack in 2 days!! Fantastic customer service (takes a lot of the fear away from ordering online). I’ve used the Aether70 in and around the Missouri Ozarks, up Mount Whitney, over the Teton Crest Trail, in and around Sequoia and Kings Canyon – rides well. In order to weight train, I hike around with 65lbs of barbells wrapped in towels. Under this load, the pack is struggling to keep up and it is uncomfortable when compared to larger heavier rigs. My normal hiking load is 25 – 40 lbs (depending on weather – a winter load includes Ice Axe/Crampons/etc) – and at this weight level, the pack works better than anything else I’ve purchased to date. Waist belt wasn’t “heat formed” but I didn’t feel it was necessary – as the belt is very comfortable. Storage was adequate – although for a 4-5 day winter trip – it is too small - need an 85. I actually use the lower compartment for my Tent, stakes, etc and ram my sleeping bag down through the top – which is a single opening. My bear canister (Garcia) fits OK. The top pocket is a little small. I can squeeze in a Nalgene on both sides using the stretch pockets. Other than that there is no additional storage pockets – which would be my only request for an improvement. I would definitely buy another Aether70.

Mold your belt at home.

First Ill get the repeat stuff out of the way. Like everybody else, Im impressed with this pack and excited to put it through some serious abuse come spring time. Like others have mentioned, for the price, you think the rain cover could be thrown in. But I digress..
The following is for informational purposes, and should not be attempted without the full understanding of the fact that you may damage your hip belt. That being said, some quick research on the properties of nylon followed by a quick prayer, and I molded my own belt by placing it on a cotton towel inside the oven for 10 minutes while monitoring the temp and keeping it between 175-200*F. Then as the osprey videos suggest, I wore the belt around until it cooled back down. It's now formed perfectly! (Oh, speaking from experience... make certain you put the hip belt on right side up, or you will be repeating the process a second time! haha)Why did I attempt this myself? Because the nearest dealer isnt worth the cost of fuel for something so simple. The oven is clearly little more than an EZ-Bake, so I felt it was worth a carefully monitored chance. I won.

BEST PACK EVER!!!!!!

Rating:*****
This pack is PERFECT for shorter overnight trips. The custom fit hip belt (that they mold to your body in the store) makes this pack feel as if it isn't there... Even after I attatched a camera case to one side and a gun holdster to the other, it was still comfy!! The straps all around are very versatile, allowing you to connect gear/equipment in several different positions to fit your needs... Both water pockets on either side are PERFECT for a nalgene... Also, the 'stretchy' pocket on the back is perfect for the pack rain fly, rain parka, first aid kit and trail mix... IT GETS BETTER! The removable top compartment works well for day hikes (after connecting to removable hip belt) and is AMAZINGLY EASY to disconnect and re-connect... THIS PACK IS EXTREMELY RUGGED!!! I took it on several weekender trips deep into the canyons of West Texas (sand stone, mesquite, pinon, etc.) and even after several slips on the steeps, it is like brand new!! I HAVE HAD MANY packs in the past (Kelty, The North Face, R.E.I., etc.) and NONE have come close to the comfort, versatility and durability of this pack!!! GO GET IT!

Great, durable pack!

I punished this pack for a week on Mt Roraima, Venezuela, and it held up much better than I expected. After several river crossings, constant rain, and squeezing through rock passageways, the material still looked as good as new. A rain cover would have come in handy though, and perhaps an external compartment for the hydration reservoir, since it was quite a pain to replace an empty reservoir with the pack fully-loaded (though this is probably common with most packs).

I've also checked this pack as luggage at airports with no damage incurred, and if it can stand up to heavy-handed abuse from Guyanese airline luggage handlers, it can do anything.

The Aether is the single most-comfortable pack I've ever used (and this was with the standard, off-the-shelf hip-belt molding - I couldn't imagine it being any more comfortable if I had actually had it custom-molded!).

The removable butt-pack/top compartment was well-intended and probably convenient in the event of emergencies, but way too much of a hassle to remove and use as a day pack very often.

The Aether is the best pack in its class, hands-down.

Osprey packs are simply amazing. I have used an external frame pack since the early 90's and switched about 5 years ago to an internal frame. Even some of the higher end Kelty's and Northface packs don't even come close to the carry comfort of these packs. I have the big brother the Aether 85. Even with 60 pounds on my back I can hardly feel it. One good thing about these packs is that they can be custom molded to your waist, and that helps a lot. Even without the custom molding this is still one of the best packs I have ever owned. Not only does it have plenty of room it also cinches down to nothing. It will carry just as much gear an external frame can but in what seems like 1/2 the space. Yes, they are a bit expensive, but if you are into backpacking or even just starting out this would be a great pack for you. I am a tight wad when it comes to money, but an Osprey pack is something I will shell out for.

Negative Reviews:

Disappointed

I was really excited when I got this pack because of all the great reviews. I went on a backpacking trip to Glacier and with weight in it the pack didn't perform well. The straps stretched out so it didn't fit properly and they kept loosening. Also one of the buckles broke on the pack the second day just from tightening it. The water bottle holders on the sides are so tight getting a bottle in there with a full pack is near impossible and they are extremely inaccessible with the pack on. The hip belts kept sliding so pressure was distributed in all the wrong places causing my knees to angle inward causing a lot of hip and foot pain as well as uncomfortable rubbing and pressure on my lower back. Make sure the pack really fits before you buy, try it with weight in it. Also if you need to take lots of drink breaks make sure you have someone behind you to pull out your nalgene and put it back because you won't be able to with it on.

Nice Pack....But

Rating:**
Went through 3 Osprey packs in a 12 month period. Seams came loose on all three and the carry handle broke on the third. The hip belt buckle broke on one.I found myself constantly trying to make the hip belt stay in position as I hikes. I did have it molded.I take very good care of my equipment and it was not abused.[...]
