Ive been looking for a pack that actually fits me. I have a very broad frame and am 6' 5". I went to REI and was fitted and was told I was vetween a Large and an XL. I always bought a karge and adjusted the length but it never fit right. Ive tried other XL packs and nothing seemed to fit right either. Until this one! This pack has everything that I could ask for and actually fits me, properly. It rests on my hips like it's supposed too. I took it for a few short 5 mile hikes with full weight and could barely tell it was on me. It felt like it was a part of my body.
I used the Aether 70 to carry my gear on a 400 mile trek from Selma, Alabama to Memphis, Tennessee following the National Civil Rights Trail and other historic sites where Dr. Martin Luther King, Jr. either pastored or led marches. During my hike the Aether 70 provided all the space I need for my belongings and more. After completing the first 50 miles I unloaded some of my gear reducing the pack weight from 43 to about 35 pounds. Overall I was very happy with the pack and especially the easy access to all its compartments. I do wish I had taken more time prior to starting the hike to get all the adjustments I needed for the weight I was carrying worked out.
This is my first backpack. I did a lot of research and tried on several at REI and it was the best for my needs. I've used it once so far on a 28 mile three night trek carrying 48lbs and it was excellent. It was comfortable, had pleanty of room, exterior pockets and straps for everything I brought and needed. It was my first piece of backpacking equipment and I had to buy everything needed to be able to do this. I did not want to replace anything or wish I had bought "the other one" so I bought as good of stuff as I could with a lot of online research and time in REI. I was happy with the Aether backpack when I got back to my car after carrying it for four days. My body took a beating as it was considered a rough trail but I can't imagine that there is a backpack that would have been better. Day time temperatures were in the low 80's with low humidity and I never had sweat running down my back or even thought about it being hot on my back. Bring a bungee cord for carrying the shoes your not wearing. I'm planning on doing the same trail again next month, October 2018, and look forward to using my backpack again. Eagle Rock Loop in Arkansas in April 2018 was my first backpacking adventure. I would reccomend the Osprey Aether 70 pack!
I had an Atmos 65 airframe. Although that pack was well built and nicely outfitted, it did not work well on my body. The back of the pack simply didn't lay close enough to my back and thus pulled on shoulders and neck and tended to throw me off balance, no matter how I adjusted it. SO, because that Osprey and my other Osprey, the bullet-proof Kode, were so well built, I sold the Atmos and got an Aether 70. And this one fits my body much better. I love the way I have to pry the hip belt open like a clam, to insert myself, reminds me of an old race car seat I had. Once in the hip belt closes as if it was built just for me. And it carries the load. I have to remember to put at least SOME of the load onto the shoulders. Another advantage of the Aether is the good idea of the top-hat that becomes a fanny-pack. This saves me carrying the extra weight and bullk of a hip pack for day-hike-peak-assaults from a high camp. But the top-hat disconnect, reconnect and belt design need a bit of rethinking or fine-tuning. The belt tends to slip, the disconnect is fine, but the reconnect not so smooth, and the overall fit of the top-hat to the pack is a bit funky. Lastly, the top-hat fabric is not tough enough to withstand fanny-pack grinding downhills. I had a slight brush with some granite on the way down an Adirondack peak and the top-hat fabric gave out at one of the seams, right on the stitching, either from abrasion or strain. But these Osprey packs are quality at high levels for sure, and there is a certain confidence and satisfaction that comes with that. I tend to carry between 35-45 lbs in my Aether, depending on the trip length and season. It handles that load range with aplomb, and rides closely to my body, to help maintain balance on the kind of rough terrain better thought of as an obstacle course than a trail. A fine tuning of the removable top-hat would make this pack as perfect as a pack can be.
First, I would like to say that my other pack is a Mystery Ranch 6500 with the NICE frame, so that is what I have for comparison. This pack is the perfect size for a three day mountaineering trip with all of the equipment needed for that purpose. Or probably 5 days of hiking. I really like the outer stretch pocket that can hold a climbing helmet and a jacket. But my favorite feature is the lid/daypack. Unlike my MR, this lid/daypack is a functional pack that includes some cool little touches such as the ice tool stash and reservoir pouch. The XL pack fits me perfectly at 6'3" and 260 lbs. It is a long and skinny pack though, so it tends to get caught up a lot while bushwhacking and can make it hard to look up the mountain with a helmet on. My biggest gripe is the comfort level at higher pack weights. I am comfortable with this to about 50 lbs, but then it really starts to dig in. My MR is comfortable even when hauling extreme loads (100+ lbs), but it also weighs twice as much. I know this pack isn't intended for that, but I would have liked it to be comfortable to at least 65 lbs given the size of the pack.
I am 6'3" and have broad shoulders, so based on the suggested sizing, I knew that I was between the XL and L frame. The XL frame was on sale at REIOutlet, so the decision was easy. When I brought the pack to the store, two experts said my pack was way too big. After trying out several packs, I ended up with a medium size. So, unless you are 7 foot and 400 lbs, don't buy the XL size.
I recently used this pack for an intensely busy 1-week trip to Alaska. This was my summer vacation and included a lot of hiking/camping in rough terrain. WHAT A GREAT PACK! Was incredibly comfortable, easy to use, and I can tell it will stand a beating over the years. I packed everything I needed in this for one week, minus a change of clothes, toiletries, a laptop, a DSLR, and 3 chargers which I kept in my carry-on just in case. That weight would have added approximately 6lbs. The total weight for the bag with all the other things I needed for a week topped out at 30.1lbs. That's a great starting place for anyone considering this back for thru-hikes or urban backpacking in Europe/Asia. Favorites: Angled access for standard size nalgene bottles on the side is a GREAT idea. The removable top which converts to a day pack is awesome too. Loved the front zipper for easy access to the main compartment. VERY comfortable on my back and easy to get through airport security for a carry on in a pinch as long as it's not totally full and. This thing is clearly built to last. Not-favorites: I am a very small male - 5'7, 140lbs, with a 30" waist. The smallest hip-belts, a male S or female XS, are still a tad too big for me. It didn't bother me hiking at all except a little rubbing on one side. But that was hardly noticeable. Not sure how the hip-belt would fare comfort wise on an extended trip over 5 days. I think it's fine but I had the belt cinched up ALL of the way with no extra left.
I've never spent good money on a backpack until this one. For years I've dealt with sore shoulders, acne on my back (from backpacking), rubbing on my tailbone, and basic features. I can't believe what a difference this backpack made for me and highly recommend it. The pack makes even a 50lb load feel comfortable with the way it hugs your hips and back, and the mesh panel breathes well and my skin is much clearer after trips. The hip pockets are large enough for a ton of small equipment or food, the day pack is functional for alpine climbing, compression straps tighten the load against your back, the hiking pole holders are super convenient, it holds ice axes well, and the dual water bottle holders are reachable and functional. I can't get over how much I love this backpack. It's really made me enjoy backpacking and heavy loads a lot more.
I actually use my bag to carry my telescope around. The scope fits perfectly in a 70 liter bag, and all the accessories fit into the pockets. I have been using my bag to carry my telescope for 6 years. I have traveled all North America with it. I just sent it back and received a new one, because the first bag was falling apart. They are made great for my telescope business. I also use it whenever I go on hiking trips, of course.
I'm not an expert on backpacking, but work with folks who are. I wanted to go on an extended outing and turned myself into a gear geek. I did my research and decided on the Aether AG 70. It's plenty large enough to haul everything I want/need. Love the various storage pockets. I went on a 5 day hike on the Foothills Trail and have no regrets on my gear. I'd buy the same pack again and suggest it to others as well.
