    Osprey Aether 85 Packis rated4.6667out of5by6.
    Rated5out of5byfromBack packersI love this pack! It is comfortable and holds everything I need. It is great for travel as well as camping and back packing. I can't wait to use it more!

    Rated5out of5byfromBest Long Distance Backpack AvailableThis is hands down one of the best pieces of backpacking equipment I have ever bought. Had the Aether for almost 3 years and there is absolutely nothing wrong with it (no tears, loose seams, etc.). Low estimate would be that the pack has been utilized for 75 days on trail, including a month doing maintenance work on the AT. I have used this pack for 8 day trips and had room to spare.

    Rated5out of5byfromThe Mountaineers Pack, hands downI 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.

    Rated5out of5byfromBest I've FoundI'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.

    Rated3out of5byfromNot a bad choiceI 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.

    Rated5out of5byfromGreat packI'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.
