by fromOsprey Ariel 75 I kept going back and forth on getting the Ariel 65 or 75. I purchased the 75 because it gave me flexability to put items inside my pack or outside. It also allowed me to put the large bear vault inside my pack. I loved being able to custom fit my pack. I needed a small pack, medium hip belt and large shoulder straps.

by fromSo Comfy! So far haven't used this on a hard-core backpacking trip yet, but will soon. I've used it for several camping trips, including one where I had to haul gear for several other people as well as my own on a mile or so hike. So far it's been super comfortable, even with heavy loads. It's very well designed. The only thing I'd ask for is a few more pockets for things like cellphones and such, but those can be improvised. I also don't really have a need for ice-pick holders or whatever some of the straps and loops are for, but never know. Other than that it's roomy, has great compression straps, good padding, etc. I got the hipbelt molded at an REI store, which I'd recommend doing. All in all I'm really happy with it.

by fromPhenomenal Pack! I recently went on a 4 day backpacking trip to Kesugi Ridge in Denali State Park. This was my first time using this pack and I sincerely enjoyed its comfort and large capacity. The pack is breathable and sits nicely for hours of hiking. I would highly recommend this pack for its comfort, lightweight, great amount of space, and wonderful looks.

by fromExcellent pack I took this to the Grand Canyon for 6 nights below the rim and loved every minute of it. I went in with about 42lbs not including the pack weight and water. The pack is highly adjustable and very roomy. I was really torn b/t the Ariel 65 and the 75; I decided to go w/ the 75 b/c I don't like cramming things into my pack and the compression in the Ariel easily cinches up smaller loads. That versatility made it an easy choice for me. The 75 will take me farther, but it will do just as great of a job on shorter trips. The pack has a lot of adjustment options. I found it was very easy to adjust and extremely comfortable. I always felt balanced with the pack on. It didn't feel too hot either, which was a plus. I didn't end up having the hip belt molded, but I found it was very supportive and comfortable throughout the trip. I removed the lid and used it as a lumbar pack several times. It was easy to take off, comfortable to carry, and easy to put back on. The lid is actually quite roomy as a lumbar day pack. I was surprised by how much it held. I ended up carrying two 2 liter platypus bladders rather than a single larger unit. This worked out great; they both fit in the pack's hydration sleeve, and I was able to run the hoses out of the dual ports included for this purpose. I didn't go for the Osprey hydration bladder b/c it was heavy and I was concerned it would be way too hot. Even in the desert, my water bladders did not get too hot. I think the molded foam on the pack did an excellent job of allowing air to circulate, which kept my back & the water cool. The straps designed to stash hiking poles are a wonderful addition to the pack. I used them several times to scramble in a few spots and they worked perfectly. Pretty much every pocket, strap and zipper is in exactly the right place. It's easy to load and easy to unload. You can get everything you need into the most convenient place so it's right where you want it at the end of your hike. I love this pack and I'm planning to have it for a lot of years and a lot of miles.

by fromYay! I mostly use synthetic materials, which tend to be bulkier than down. I got tired of having to stand on my head to compress everything, so purchased a larger back. SOOOO happy with that decision. The additional volume aides in ease of packing, organization and quick loading in the rain. The features are nice and the stretchy pocket on the front is a godsend. I haven't used the heat forming waist belt yet, but it fits great without that and, like my last Osprey, you can't even tell you are wearing it. I especially LOVE the airvented back. Another godsend. My one gripe, and it's a big gripe, is that it doesn't have a built in pack cover. Seriously, ax pick hooks, super cool quick stow Leki hooks, even an outside pad hook but no pack cover? Uncool. And, it is a little heavy, but only a few ounces more than the 65L and worth every ounce! And did I mention comfortable?
