Rated 3 out of 5 by from not the pack for me I bought this a week or two ago and have been fighting with it ever since. I traded the Aura in to try this out since it has so many good features - main compartment zipper, brain converts to a daypack, memory foam in the shoulder straps and hip belt, and the option to use the internal or external to the main pack hydration sleeve. However, it seems no matter how I pack it, the weight distribution is off and too much on the shoulders, the sleeping bag compartment fights me every time I try to pack the sleeping bag in it, the bear vault doesn't fit in the pack if I use the interior hydration sleeve but if I use the exterior sleeve the air movement in the antigravity mesh becomes nonexistent. It's also 12 ounces more weight than the Aura. While I'm aware I need to "break in" the memory foam straps and belt, it's not as comfortable as the Aura right off. I'll miss the good features of this pack, but it's just not worth fighting with it. I'll be going back to an Aura. This is a good pack for somebody, but not for me.

Rated 3 out of 5 by from Lots of Compartments but Not Enough Room? I bought this pack to go on my first backpacking trip. Pack itself looked great. There were a lot of compartments, zippers and straps. However after packing it with the help of an experienced backpacker, it didn't seem like it fit much. At baseline compared to my fellow backpackers, even though we were carrying relatively the same items (I may have even had less stuff) my pack felt a lot heavier. The suspension and cushion definitely helped with the load. I am disappointed that the mesh at the front of the pack ripped with my first ever trip using it; there wasn't anything that was remotely sharp so not sure how that happened. I thought pack materials were supposed to be durable.

Rated 5 out of 5 by from Good Fit I purchased this pack for a four-day pack trip in Colorado in July. Preparing for this trip, I've used the pack several times on shorter hikes and have been impressed with its fit, ease of adjustments and quality. The weight is very evenly distributed and the hydration system was easy to use. My only complaint, and it's a small one, is that the zipper pouches on the waistband are nearly impossible to zip closed when the pack is being worn. The salesman at REI was very helpful in getting the fit just right and making sure I picked the best pack for my needs. Good product. Good customer service.

Rated 5 out of 5 by from Updates make it everything you hoped it would be I had the first version of this bag which had some cool features, but was definitely in beta. This bag, with the removable lid that turns to a full backpack for day hikes, and the top loading as well as front access, with the even more comfortable waist belt is everything that I hoped it would be. I can use it for anything, from an overnight camping trip to a longer hostel based adventure. I absolutely love it and recommend it to anyone!

Rated 5 out of 5 by from So comfortable! This is my first real backpack is 20+ years and, wow!, have they changed! I'm glad I got fitted instead of buying online as I would have purchased the wrong size. I'm 5'3" and purchased an xsmall. The frame was adjusted in REI to fit me specifically and I cannot complain as it is perfect! I put it on, make the connections, pull the straps tight and I'm ready to go. The internal frame is a dream. It doesn't poke or prod and doesn't feel heavy. I've only worn it a handful of times, but it already feels as if it is molding to me. The hip belt is comfortable, but sometimes rides up slightly if my pack is on the light side. I could adjust the pack to compensate for that, but haven't as it hasn't bothered me thus far. Shoulder straps are in the perfect position and don't rub under my arms. I can tighten/loosen the straps with the quick release easily. There are pockets on the side for water bottles, but I haven't used them yet as I prefer the internal water pack. The water resevior has it's own compartment and is integrated into the pack. Love this feature! I'm sure I'll appreciate the water bottle pockets on longer treks. The sleeping bag compartment is in the right place at the bottom of the pack and I like that I can stuff it from the bottom of the pack. There is a false bottom between the sleeping bag compartment and the rest of the pack. You can also remove the top part of the pack and use as a daypack (haven't tried this yet) and there is storage for trekking poles, another nice feature. Additionally, there is exterior pocket that is easily accessible when the pack is off for snacks, bandanna, etc.. The hip belt pockets are small, but I like them for gloves, compass, and sunglasses. I looked at a lot of packs online and liked the reviews on this one. I was sold when I went into REI and they had it in the store to try out. Great aesthetics too - I was torn between th blue and gray. I bought the gray and it is beautiful! I look forward to some multi-day hikes in this pack. I hope it holds up well over time.

Rated 5 out of 5 by from First backpack I bought this for my first backpacking trip and it was awesome! I was back and forth a lot but so glad I went with this bag in the end. Worked great and super comfortable.

Rated 5 out of 5 by from Spacious, comfortable, durable. Bought this pack recently in preparation for a backpacking trip to South America. In order to break it in and make sure it worked well, I took it on the Lost Coast Trail in CA. While Lost Coast isn't necessarily the best litmus test trail due to being mostly level and only 3 days/2 nights long, I was really impressed with the comfort of the pack! I was able to fit my sleeping bag, tent, bear canister, food, and clothing very comfortably. The hip belt distributes the weight well and takes the strain off your shoulders. Also, because it's padded, it doesn't rub against my hip bones like some other packs have in the past. The back is breathable and the sleeping bag compartment in the bottom makes for easy setting up and tearing down of camp, without having to take everything out every time. The bar on the top of the frame is indented, which leaves room for head movement while walking (rather than the kind that smack against your head with each step/prevent you from looking up). The day pack feature was a big selling point for me too. It was also incredibly helpful to have a built-in water pouch. All in all, this bag is worth the investment. I was really excited with how it performed, and feel optimistic about it serving me well in South America!

Rated 2 out of 5 by from Strangely a let down This pack has so many great features, but I have used it now for over 14 days and still the waist belt and shoulder straps are horrendously uncomfortable. In general the waist belts fold flat to the pack and are difficult to pull away to wrap around your waist, and the shoulder straps dont have enough length to them. Also the sleeping bag compartment is too narrow for any of my bags except for my 40 degree. The pack also advertises that it makes your load feel lighter which i dont find to be true, probably due to the uncomfortability and lack of flexibility in the shoulder straps. The brain was a really cool feature as well as the bladder! But the pack weight in general is much heavier than comparable packs.. so not worth it in my opinion. Will be returning. Osprey, combine this pack features of the day pack and bladder with some of your other pack designs.

I don't see the external zipper to the main compartment on the side, as shown in the video, for the Ariel 75 AG pack. Where is it located? The video also says there's an external & internal H2O sleeve, but there is mixed info on REI's site, which is it?

Asked by: trillmix
The model we sell does not have the side zipper. The hydration is set up as internal with the hanger and the reservoir. There is an external sleeve behind the mesh back panel that could be used for a reservoir.

I wanted to view a viseo of the pack but I guess its not available. The description states it has a external sleeve for water bladder . Where is it located?

Asked by: gwvolfan11
​The hydration reservoir sleeve is against the back panel on the inside of the pack.

I just bought the Ariel AG 65 with hydration pack. I want to clean the bladder but cannot figure for the life of me how to get it open to a( clean and b) add water. I can slide the grey clip at the top off but there is no opening there either. Help!!

Asked by: Leanne
To open the reservoir slide off the gray clasp at the top then fold the clear plastic up, and peel the edge underneath apart (it will be tight at first). Once you get that open you are then able to add water and clean; for detailed information on how to clean and care for your reservoir please refer to the article below:

What is the biggest difference between this pack and the Osprey Aura pack?

Asked by: Packer16
This pack does have a few extra features that the Aura does not, such as the J shaped zipper, and the interchangeable heat moldable hipbelt. However, the added features do make this pack slightly heavier than the Aura.

I am inquiring on which pack would be best for me. I need a pack big enough for a two-three week trip. I have scoliosis so I'm wondering if the aura Or the Ariel would be better? I know there isn't a huge difference.

Asked by: Gib17
The weight you are carrying will make the big difference. The Aura 65 will carry 30 – 50 lbs. comfortably. The Ariel 65 will carry 35 – 60 lbs. comfortably. If you are not pushing 50 lbs., you can go with the Aura and save 14 oz. (size medium) pack weight.
