I Really like this backpack, it was very comfortable and fit well.
It performed perfectly, fit all my stuff and was very comfortable loaded up to the max.
We hiked 4 miles in to the Blue Lakes and the bag was very comfortable with a 40lb load.

I used the backpack on a 50 mile hike on the Appalachian trail in North Carolina in April 2013. I carried about 30 pounds and the pack made it seem like 5. The load transfer to the hips was accurate and comfortable. The shoulder strap pads and back of the pack NEVER got wet with sweat (I still find that amazing) and the adjustable shoulder, hip, chest and load straps allowed me to refine the fit so that nothing hurt. The removable top was used as a pillow which was useful. I never used it as the daypack hipbelt that it was meant for, but under different circumstances I could see how it would be useful. The multitude of compression straps kept the load tight which allowed me to keep a good centre of gravity and hence a good balance throughout the hike. The bag material is tough although not waterproof. I kept the sleeping bag in the bottom compartment where it was meant to be, but inside a waterproof bag which gave me piece of mind. I bought a raincover at Walmart for about $5 which fit fine and kept it dry in the rain. 70 litres was more than sufficient for the 4 day hike carrying the sleeping bag, mattress, tent, food, clothes, cooking set, first aid kit and miscellaneous items. The exterior water bladder sleeve was handy and perfect for the Osprey 3 liter bladder that I purchased separately. All in all, a good product that enhanced my hiking experience.

I recently realized that I use these reviews to buy almost everything in my life, but have not given back to the community with my own reviews as much as I should, so here goes:

I am 6'4" about 240 lbs with a wide chest about 48". My torso is about 21"

This review is for the Large size in this pack.

The Large fit my torso perfectly.

I really wish people would start stating their size and the pack size/size of what they're buying more in reviews, it really helps me when another big/tall guy gives me stats, I would think it would help for people of all sizes. What's good for the average size person, really doesn't matter to us big and tall types, and vice verse I would assume. The more info the better, especially on sizing.

I will start by saying I returned this pack. I gave it 4 stars because I didn't want to hurt the rating and I didn't want to give it 5 because I feel you have to actually use the product to rave about it. The 4 stars are because this is obviously a quality pack, Osprey makes great packs, I use the Manta 36 daily.

So why did I return it you ask - Simple, I was between this and the Gregory Baltoro 75 and although it was a close one, the suspension of the Gregory won out. Simply put I felt like the Gregory displaced the majority of the weight of the pack to my hips - I'd say 75% Hips 25% Shoulders.. whereas the Aether was about a %50/50. It was 100% noticeable, especially the more weight I put in the packs to test.

The Aether is a more vertical pack - meaning it's slim and tall. The way the suspension curved it brought the top load into my head, I'm sure I could adjust straps, etc. to change the placement of the top pack, but I found it mildly annoying.

I'll admit, I haven't said the best things about Osprey over the years. I've never liked their small-to-mid sized packs and always turned to other brands for that size range, so I never bothered to explore their other product lines. However, I keep an open mind and was quite astonished at how well Osprey excels at making larger backpacks. Let me outline what some of you may be going through:

Using larger tactical style bags for many years, I decided it might be time to look into an actual backpacking backpack. If you do any research on 60+ liter backpacks for hauling 45+ pounds around the $300 range, you'll typically land at the same four: Osprey Atmos AG, Osprey Aether, Deuter Aircontact, and the Gregory Baltoro. I tried them all and found the following...

The Atmos AG is really designed for a person with a very thin build using it in hot climates. I do not have wide hips as a guy, and it was almost painful to wrap the waistbelt around me because of the tension on the mesh. I have also read that when you are trekking through the snow, it can build up underneath the mesh and before you know it, you have a huge icicle on your back (although since it froze conforming to your body, I suppose it would be a very comfy icicle). This is one of those love it or hate it packs -- I can see how this would be phenomenal if it fits you right in the intended weather conditions, but it was not for me.

Next was the Deuter Aircontact. This is probably the most durable in the pack lineup between the rugged construction and bombproof harness system. Unfortunately, I wasn't a fan of the mesh material used for the padding, the zippers were very difficult to maneuver, and it just wasn't as comfortable as I thought it would be.

I have to preface this by saying that before this purchase I was using a borrowed pack that was far too small and had a poor suspension system...

That being said, this pack is everything I wanted with none of the excess. Tried on multiple packs at a local outdoor retailer before deciding on the Aether. Narrowed my choices down to this one and REI's Crestrail 70. Aether fit me better so that is what I went with. People have complained about the lack of interior organization which has not been an issue for me. The cavernous interior swallows enough gear for (IMO) a weeklong trip. I have a tendency to overpack for weekenders and had plenty of room for my kit including a 10+ year old gargantuan synthetic bag, 3L platy big zip, clothing for temps in the low 20's (many layers since I don't do down), machete, shovel/pick combo tool, Alite monarch chair, 1L nalgene, cook set, stove, among other things. The side and back stretch pockets expand to fit quite a bit. Haven't used hip pockets yet but they did not pose a problem as far as mobility. Detachable lid is a great feature that I thought I would not use. However, keep first aid/survival gear and snacks in there to have on short hikes out of camp. Also store the pack with lid inside.

To sum it all up: if you are looking for a large, customizable pack that is extremely comfortable...GO FOR IT!
