Best I've Found

I've had this pack on my back over 50 days this past year and it continues to impress me. Makes heavy loads manageable. The fabric is stout and shows no signs of wear even though I've bushwacked and scraped countless rocks.

This pack also eliminates the need to carry a "day pack". It is narrow enough to stay out of your way on steep terrain and can be cinched down quite small when not fully loaded. I have carried it half-loaded as my airline carry-on many times and never been flagged for its size.

It has some features that I never use, like the cargo zipper that allows access to the middle of the pack, but that extra ounce or two of weight doesn't matter when the pack is as comfortable as this one.

My one complaint is that Osprey's volume claims always seem optimistic to me. I have the 85 liter but can fit the same or maybe a little less than a 75 liter I had from another manufacturer. Having said that I can still fit enough gear for a 14-day solo trip in this pack. I would consider getting the Xenith 105 but I can't convince myself to spend the money since Osprey's lifetime warranty will replace this pack if I ever manage to break it.

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

The Mountaineers Pack, hands down

I purchased the Aether Gen. 1 six years ago. I have summited with it on Rainier 7x's, Orizaba 3x's, Elbrus, Aconcagua and Denali. I have owned this model (Gen 4) and the improvements are what you would expect from Osprey. For the mountaineer who needs a voluminous pack for an expedition and then compress it down on summit day, this is the pack. No useless pockets, zips or buckles. Just the right weight and form for any extended day peak bagging excursion.

Great pack

I've used this pack twice now and it's been great. Last pack was a Kelty Coyote and I wanted something a little lighter with comparable storage/external pockets. This pack fits the bill. It does ride a little rough on the hips, but that's probably because I need to go back to the store and have the hip belts molded more. Otherwise no complaints.
TNBackpacker at REI on 02/02/2013

I got this pack form rei not here and the 2012 model but the 2013 model has more features. There almost identical and it stores all of my gear weather i need it or not just amazing pack.

Not a bad choice

I have had this pack for a while now and taken it on several excursions. I do like the style and options of the pack, like the hiking pole holders are very handy. What especialy do not like about this pack is the weight, its not something i considered too heavily before i bought, i wish i would have. Im going to go with a lighter pack this one just isnt cutting it for me.
