Description

Sized right for long weekends in the backcountry, the Osprey Aether 70 Backpack for men emphasizes the importance of comfort and support with an innovative AirScape Suspension. The AirScape Suspension utilizes dual peripheral aluminum rods to help stabilize the load of your outdoor gear and transfer the weight close to your body. Like other backpacks in the Aether (and female-specific Ariel) series, the Aether 70 offers male-specific IsoForm harnesses and hipbelts in multiple sizes. These harnesses feature spacer mesh with no sewn seams to help prevent chafing. The IsoForm CM™ hipbelt can be heat molded for a custom fit, too. Other features include a top pocket that converts to a lumbar day pack, J-shaped zipper for complete access to pack contents, sleeping pad straps, hiking and backcountry tool attachments and an internal hydration compartment (hydration system not included).

great pack
January 09, 2008

it holds a lot, without being too bulky. i bought it for my friend who was moving to italy and he loved it. found it to be a very efficient pack for his travels.

Comfortable!
October 21, 2007

I have an Osprey Atmos 50 backpack for one to three nighters but I could not get my big bear canister inside. The Aether 70 can hold the bigger bear canister and is the pack I use when I'm gone for 3 to 6 nights and I need to carry a big bear canister. I used this pack for a 6 nighter in Emigrant Wilderness this last July and was very pleased with how it handled and the weight it carried (45lbs)... a very comfortable pack

Perfect
May 25, 2010

This is an extremely well designed pack. I'm very pleased.

LOVED IT
June 12, 2006

I got this pack primarily for use rock climbing. Did some homework and found Osprey had an excellent reputation and tried some on in stores (this pack was not available in stores I went to) and I liked the suspension and back air-mesh. I got a medium size and right away found that the hip belt had to be cinched down all the way to fit my waist (about size 31). Still, it fit and after making a few adjustments to the shoulder straps, I'd say it was a perfect fit. The thing I was looking for in a pack was one that I could access very easily. For example, if I wanted to just access my climbing rope or just my rack, I could open the pack at either end. Also, the two could be separated. The sleeping bag compartment accomplishes this. With rope, rack, water, layers and food, my pack weighed in close to 40 pounds. The suspension provided by Osprey gave me no problems carrying the weight. I got the pack just before a trip to Yosemite and didn't bother with the "custom molding" hip belt since I thought it fit just fine. Can't imagine how the fit could improve. Very comfortable and there's many adjustment possibilities. I haven't looked in to it, but wondered if you got the belt custom molded - what if your waist shape changed? During my trip, the longest hike I did was about 1 1/2 hours, but it was pretty steep and hot. The pack was fully loaded and I had no problems. I also climbed with the pack on (3 pitch). Initially my climbing helmet kept bumping in to the pack when I looked up, but I just loosened the top straps used to pull the pack snug to your shoulders and the problem went away. When climbing with the pack, most of the stuff typically on the inside was on the outside. Again, no problem because of the many straps on the pack that you can use to cinch it down. I took off the top pouch and used the hip belt as it says you can for short hikes. The top pouch is large enough to hold my 100 oz. Camelbak, a small first aid kit and other odds & ends with MUCH room left over. I was surprised at how comfortable it was. Removing the hip belt isn't all that bad but you have to dig between the belt and pack to separate the Velcro. I don't know another way for them to design it, so I guess it has to be that way. The feature worked out great. If there's any drawbacks to this pack, it might be the weight. But that's a non issue for me. I wanted something more sturdy and these materials do the trick. The compartments separate my rope, rack, clothing layers, first aid stuff, maps/books, lights, etc. very well. It's one of the few packs that I found I can reach the two exterior lower side pockets without removing the pack because of the holes. The only other possible improvement that I could think of was if they did like Camelbak and created a separate access for the hydration system. As it is, you have to access the hydration through the top and if the pack is really full, it could be inconvenient and you might have to remove some stuff. But as far as I know, most if not all packs that offer a hydration pouch are designed this way (again, with the exception of Camelbak). The pack is slightly large for my needs, but again, I wanted the organization options and couldn't find it in any other packs except the Cerro Torre 47L. That pack was slightly too small for my needs and wouldn't work in colder conditions because I wouldn't be able to bring along too many layers. This is the best pack I've ever owned and I'm looking forward to having it burried with me.

Great backpack
September 03, 2012

I got this pack during the labor day sale and testing it on a 2 days local trip hike. Even though it is a overkill for such a short trip, it is very comfortable and the compression strap works well in packing my stuff tightly. The padding is well ventilated to help deal with sweat. There are plenty of space and will serve me well for my up coming 4 to 5 day backpacking trip in the Yosemite/Eastern Sierra's. The ego hip belt feels good but I have concern of where to get it custom fit since I got this pack online. Also, I wish there is a pocket on the belt for quick access of personnel items. Overall I like this backpack very much and will recommend it.

Pros: Great design, Build quality, Performance

excellent
July 30, 2007

hiked ~ 5000 ft(9000 - 14,000ft) in Bolivia on first use of pack without having belt custom molded. Was able to adjust pack for extreme comfort. I would recommend highly.

Wow, what a great pack
January 05, 2007

I was really impressed with how it fit to my body. There are lighter packs, but I feel that because this is such a good fit, some of the weight hides itself in comfort. The materials used are burly. I like the stretch pocket to store wet stuff. Solid hipbelt and suspension system. Great price, especially on sale.

Great pack, so far...
December 08, 2010

After falling in love with my Atomos 50, I went ahead and picked up the Aether 70 for backpacking and mountaineering purposes. Although I've yet to take it into an alpine environment, it's been flawless on several multi-day backpacking trips this past summer/fall. All compartments and straps are logically placed and no redundancy; the status quo for Osprey, from my experience. Favorite features include access to the main compartment via three separate points: the upper draw string, the J-shaped zippers on the middle of the outside and the sleeping bag access at the bottom of the outside. The trekking pole loops were also handy. A few things that weren't necessarily "cons" but that I did notice: heating of the waist strap didn't really help much in terms of comfort for me, and probably wasn't worth the effort. Also, the detachable pack on the top is marketed as a summit pack/ day pack but I felt it was lacking in capacity for my purposes. I remedied this by purchasing the Daylite pack, which can be integrated into the Aether using existing straps on both products. In addition to adding capacity (~13 L) to the Aether, it also proved to be a much more capable summit/day pack. Overall, an awesome pack though. Would highly recommend it to anyone and I can't imagine it failing me when I eventually use if for mountaineering.

Pros: Great design, Build quality, Performance, Great value, Cons: some redundancy (straps)

Amazing bag
January 26, 2012

I'm in the military and this is my first non issue Osprey pack... needless to say, I wish we were issued these packs... absolutely awesome bag. Bought the smaller Aerial for my wife and she loves hers too! DEFINITELY RECOMMEND!

Pros: Great design, Build quality, Performance, Ease of use, Cons: Cost

Great all-around pack
June 01, 2009

Perfect for a long-weekend camping trip. Lightweight, comfortable (even when fully loaded), and plenty of room for all your camping gear. Plus, it held-up very well during my last hiking trip - even though it got quite a bit of use and abuse.

Most Excelant Pack
July 24, 2009

I have to say Christi in customer service was a super star in getting me this pack. I got it two days before going to Emigrant Wilderness. Most comfortable pack ever. I used the top as a day pack and it worked as designed. I read all the instructions twice to really let all the options sink into my noggin. One thing Osprey left out was that the hip belt can be moved up or down about 3 inches (I noticed this after using the belt for the day pack). I am 6' 3" with a long torso and when I put it all the way to the bottom for the trip out, it was EVEN more comfy!! LOVE this Pack.

Great pack, Innovative Design.
August 10, 2006

This pack is new this year and is hard to find due to demand and distribution problems at Osprey. I was happy to find it at Altec. I bought the Aether 70 because my ultralight pack was ultrawimpy. For a pound more, you get a super supportive frame system and a real hipbelt that can carry 40-50 lb loads for weeklong trips. I took it to the local REI and they kindly baked the hipbelt to custom fit my waist. Nice. I tested it out on a 3 night trip near Tioga Pass in Yosemite, and it felt great on 2500 foot climb. Im not sure where the other reviewer gets the cheap material comment. I think the fabric used is fairly heavy-duty and better that material used in most lightweight packs. My only negative comment would be about the top lid/lumbar pack feature. It's kind of a pain to get the hipbelt off and onto the top lid, and barely worth the effort for the small top lid capacity. Overall, a great pack at a great price.

Osprey hit's a home run
August 13, 2010

Just bought the 2009 model on the "outlet" portion of the Altrec site ($100 off), and I couldn't be more pleased. I've hiked primarily in a 2005 Deuter 65, and decided to go for an upgrade before heading to Tanzania and South Africa for a month. The pack fits like a glove, and after a few quick hikes there's no rubbing or chafing (size S, 5'7", 140lbs), and I haven't even had the belt custom molded yet. Also the pack is extremely light and breathable, and with Osprey's compression system it can hold a variety of weight without looking bulky. I also bought the Osprey MEDIUM Rain cover and it is plenty large enough to cover the pack and the bedroll. Don't be tempted to go any larger! Overall the pack is a steal on the outlet portion of the site, try to catch them while you still can!

Very very comfortable
May 09, 2008

Took it on its first trial run. I was very impressed with this bag's many tightening straps that held the load very steady. Also, the daylight attachable attaches very securly and is very convenient.

Great Pack For A Great Price
May 27, 2007

The Aether 70 is the perfect size pack for weekend/week trips. The weight distribution makes 40-50 lbs feel extremely comfortable. I love being able to use the top pouch as a lumbar pack. You are buying two great packs for the price of one when you get the Aether 70. A lightweight and durable pack, well worth the money.

simple, sturdy pack... minimal features
May 10, 2010

ergonomically, osprey is dead on. the airscape back ventilation is bomber and the foam on shoulder straps is dense and wide. the pack is narrow and close to the body. the only drawbacks are no inner pockets ( like a small envelope to hold keys etc.) or no zippered pockets internally to hold valuables. also, the frame curves away from head allowing ample space, but this infringes on packing space. the aluminum frame juts into main compartment and makes packing above this line difficult. the pack has good compression straps if loaded fully, but not much capacity to compress if partially loaded.

Super pack
September 15, 2008

Pack is very adaptable to changing loads over the course of an extended backpacking trip. I would recommend it to serious backpacker who are concerned about weight.

Great Pack!!!
January 05, 2010

Bought this for my boyfriend and he loves it! He is 6'3" and he says it fits him perfectly and that he has plenty of room for all of his gear. He says he is recommending it to all his friends!

Great Pack
April 14, 2010

Great pack for carrying heavy loads, it has a nice balance that moves most of the weight to your waist. Very roomy too; the new front access zipper to the main pocket is a nice new feature!

You can't go wrong with this one!
August 16, 2009

I love my pack. I would like more external/quick access pockets. I have taken it on several 3 day trips and it is just great. I love that I can pack it out or sinch it down for a lighter load. We have three Osprey's in my family and we are all very happy with our packs.

February 16, 2011

the bag is very nice. i love the feature especially the top pocket that can be a lumbar pack. it is very suitable for more than 4 days hiking. you can make sure all thing that you have to bring for your activity fit in the bag.

Pros: Great design, Build quality, Great value, Cons: Wears quickly

Perfect Pack
June 27, 2008

Hiked all over Southern Mexico with this pack and it held everything I needed and was very comfortable. I definitely recommend this pack or any Osprey pack for that matter.

Great, Comfortable Pack on weekend trips!
September 20, 2006

I bought this pack to take on two to four night treks into the woods. It is well constructed, rugged, and very comfortable. I researched several different packs to determine what fit my needs best. This pack was a little on the small side in terms of storage but I couldn't pass up its well thought out construction. It is very light. Fits all the gear I need for a weekend trip even when I pack uneccessary items. For trips over 3 nights you definitely need to be concious of what you are taking but you can make this pack work. I used it throughout the Adirondacks this past spring and was very pleased. The hip belt can be heat molded to your form (which I recomend) and the top lid cover converts to a lumbar pack with the hip belt. Very cool feature when you don't feel like packing an additional day pack on base camp trips. Lumbar pack has enough space for day treks and since it uses the hip belt it is really comfortable. It also holds your platypus which works well. I have also found Osprey great to work with if you have a warranty issue or need replacement parts.

Great Backpack
October 08, 2012

I recently took this backpack out on it's maiden voyage into the backcountry. It held up very well and fit very well. I managed to carry around 55 pounds on the way in and it was definitely at its max.

Pros: Great design, Performance, Ease of use

Great Pack
March 10, 2010

So far I've only used it for 2 weeks. I loaded it up with 45 pounds and walk the dog 3-4 miles every night to get in shape for summer hiking season. Took a few days to get it all adjusted properly. I could have taken it somewhere for a proper fitting and saved the trouble but I like to figure it out myself. I'm really quite pleased - very solid pack without too many compromises for weight savings.

Innovative Design will make this pack a top seller.
August 09, 2006

I had trouble finding this pack anywhere due to high demand and distribution problems withh Osprey. Was very happy to find Altec had them. The problem with many "ultralight" pack is they offer no support. A thin, single stay and a flimsy hipbelt offer little support when hauling a week's worth of food. For an extra pound the Aether 70 provides a solid suspension system and honest-to-God hipbelt.I took the pack into the local REI and they kindly "baked" my hipbelt to conform to my waist. Sweet. Im not sure where other reviewers get the "cheap fabric" comments. It's heavy-duty compared to many of the fabrics used on lightweight packs. I would trust this pack on any trip. The only criticism I have is with the top pocket/lumbar pack feature. It's a pain to pull out the hipbelt and fit it into the top pocket. I prefer the top lid waist straps that are sewn-in on my Gregory pack. Overall, the Aether 70 is a great choice for a lightweight pack that can do it all.

Versatile/Comfortable Pack
July 01, 2008

Just returned from a 5 day, backcountry,Yosemite trip. Loaded Aether 70 with just under 40lbs. of gear including bear canister with no space issue. I am 5'6" and 140lbs., male. My torso measurement is 18.5". I purchased a medium which puts me on the smaller side of the scale. I was wearing the pack probably lower on the hips then recommended but needed to so that there was no gap between my shoulders and the shoulder straps. I like my pack tight. End result, blisters just below the belt line on my hips. Adjusted pack to ride higher on the hips thus solving problem. The pack, even when packed full, maintains a thin/tall profile that I found helpful on narrow paths and switchbacks. Quality and craftmanship of pack appears top notch. I have yet to have the belt custom molded and plan on doing so before the next adventure. I would recommend this pack to anyone, just make sure sizing is correct.

Exceeds my expectation! Quality craftmanship throughout! Im 5' 4" with a stocky build and have tried on many different packs, this one is by far the most comfortable. Easy to load and unload. Well thought design that looks as good as it feels on the back. First class product!

March 06, 2010

Without a doubt the most adjustable load bearing pack I've owned.

Versatile, light, and comfortable, but not very sturdy.
July 26, 2006

Many great reviews convinced me to purchase this backpack. Although I am generally happy with it, not all of my expectations were fulfilled. I used Aether 70 for a 10-day hiking trip in Eastern European mountains. First thing I noticed was that the pack was very light (+) and that it contained numerous compression straps that allowed me to adjust its size for a wide spectrum of loads (+). The suspension is wonderful and the pack felt great on my back, due to the patented air-padding they use (+). However, the fabric the whole backpack is made of feels a bit thin and "cheap." In fact, I noticed a small tear on the inside of the pack, where it was chronically stressed during the hike (-). Osprey also boasts with the hipbelts that come with their packs. These may be great if you have them professionally adjusted for your partucilar waist, but having not done that, the belt felt awkward (-). Also, the osprey buckles had a tendency to spontanously open up on me during the hike (-), despite me making sure to fully click them together. I do admit that I might have over-loaded the pack, and that a 10-day hike would merit Aether 85, rather than 70, altough I don't think I carried more than 40lbs during my trip. Anyway, I believe that Osprey Aether 70 is a wonderful backpack for short-term (<1 week) outdoor activities. It is incredibly versatile and light, but perhaps not as sturdy and reliable as some of the other packs in it's cathegory.

Quality construction and excellent materials
February 20, 2010

Every year I hike the Grand Canyon and I have been using a 10+ year old other brand pack that never quite fit me correctly. Last year the interior waterproofing started peeling off and covered my gear with flakes of material and that was my trigger for buying a new pack. I had previously bought an Osprey travel pack for a Peru trip and was extremely happy with the quality of material and construction. After 2 weeks of planes, trains, buses and boats the Osprey pack still looked new! My GC trip is not until April but I have loaded up my new Aether pack and it is very comfortable even before having the hip belt molded. I selected this Osprey pack for the bottom zippered sleeping bag compartment. I do not want to unload my entire pack just to get to the sleeping bag. Looking forward to many years of use from this pack!

Perfect in every way!!!!
July 28, 2009

Bought 2 of these for my son and I to use on a 11 day trek through Philmont in New Mexico. The size was perfect for our gear! It swallows gear when needed but closes down nicely for shorter trips and fits great to the body. Would not change a thing!

Legit Pack!!
March 01, 2009

Well I just used my pack for the first time this weekend and mostly all I can say is GREATNESS! It met my every need from being big enough to being comfortable and being weather/snow proof. I used it for a weekend trip, hiked in Friday at night then about 5 miles Saturday and then nearly 5 miles after it had snowed all night. Everything stayed dry with the snow that had fallen on the pack from falling off trees. I got the orange and I'm not a huge fan of super bright colors but this pack looks great and works even better! I guess if there was any down-side it was that the shoulder straps could be a bit more comfortable, but I can partially blame it on my body being that I am not super bulky/meaty around the collarbone or shoulder area, but being a hiker I pushed through the little bit of discomfort and everything was alright! I would recommend this pack to all! Enjoy!

Looking forward to more trips with this pack.
September 17, 2006

I have been nothing but impressed with the Aether 70. I just returned from a 4 day trip in Maine and found that this pack carried 40-45 lbs very comfortably. I have not had the hip belt customized and like a previous reviewer am not sure how this pack could get more comfortable. It is strong and supportive, easily adjusted and solid. I logged long days over rough terrain and have nothing but praise. In fact, I looked forawrd to my trek back down just so I could carry it again to make sure I had not been dreaming. I hadn't. Two hiking buddies are now looking at new Aethers......I made them give mine back.

Very light and well designed.
September 29, 2006

I used this pack on a backcountry trip in Yosemite and it performed great. I didn't mold the hip-belt, so I encountered a little bruising of the old hip bones, but not as much as my old pack. I'm going to try the molding to see if it helps. Overall, a very well-designed pack. The mesh pockets stretch to hold just about everything, the latches and buckles are intuitive, the size is perfect for multi-day hikes, and the convertible top eliminates the need to carry a day-pack. My only complaint is that the suspension squeaks -- a lot.
