    So this is how a pack should feel.

    When Osprey designers engineered the multi-day Women's Ariel 65 Backpack, it included everything learned from 20 years of building and testing packs specifically geared towards the female anatomy. The LightWire peripheral frame provides support while keeping pack weight to minimum, and the IsoForm waist belt can be heat molded for a customized fit. Add in the comfortable Airscape back panel and a removable lid that doubles as a day pack, and you're set for everything from quick weekend getaways to week-long treks.

    To improve convenience and efficiency on the trail, Osprey equipped the Ariel with a top-loading design and large J-zip front panel to grant easy access to deeply buried layers while you're on the trail. Then, it added a detachable top lid that doubles as a summit pack when you need something to carry water, lunch, and a camera to the summit. A front panel can be used to carry a light rain jacket or sleeping pad, while multiple straps along the front of the Ariel secure everything from ixe axes to trekking poles.

    My First Pack

      My husband picked this out for me for my first pack. He took me on an over night trip up East Canyon. This pack has all the bells and whistles. I'm still getting used to hiking around with so much weight on my back. I had a great time and the pack seemed perfect. The customized shoulder and waist straps were very nice. Fits me much better than his old pack. My husband about lost his mind when he saw that the top turns into a fanny pack. Very exciting. Great pack and I can't wait to go back out when its a little warmer.

      Perfect pack

      • Familiarity: I gave it as a gift but have feedback to share

      This is the best option for anyone looking to get a great backpacking backpack. Osprey cannot be beat in this category and this is one of their best packs. You can load it from the top and front, but you also have a sleeping bag compartment in the bottom. The adjustable suspension system is also a great feature that can help those who are in between sizes, the back plate allows for some adjustability. This is an awesome pack with ample padding for long treks.

      Ariel 65 - Summer Wheat Brown

      • Familiarity: I've used it once or twice and have initial impressions

      Let me preface by saying that I have the Ariel 55 from 2007, and that was the only backpack I've ever known. Not a ton has changed from 2007 to now but what has was very important for my recent trip to Iceland.

      I knew I needed an upgrade for this trip because every time I was taking my old Ariel out, I was using it for either general travel or hiking trips to hot places where I didn't need a sleeping bag or sleeping mat.

      This trip was different. I had to pack 4 days of food & cooking gear, sleeping gear, and variable weather gear - and boy am I happy with my new Ariel!!!

      My Marmot Trestle 15 sleeping bag fit snugly in the compartment of the bottom of the Ariel 65 - when I first tried it out at home, I almost thought I need a bigger bag because once your sleeping bag is in, you lose (obviously) a ton of room for the rest of your gear. But I'm glad I stuck with a 65 - I learned how to manipulate and maneuver my stuff to all fit.

      The J-zipper at the middle of the bag let me easily reach food and cookware for mid-day lunch, while I used the top zipper to reach added layers for warmth or rain.

      I hike with trekking poles, and I loved the pole stow-away feature ONCE I figured out that the elastic hold can be tightened so the poles aren't slipping out the whole time.

      Lastly, when I bought the pack, I spent about 20 minutes cursing to myself that my phone wasn't going to fit in the hip belt, but thank god I didn't give up! On the underside of the belt there is a small fastener you can unhook the pocket or loosen it - once you loosen it up your iPhone 6 or bigger can finally fit! On the other side I kept a small sony camera, chapstick, granola bars and extra ziploc bags for rain protection.

      Overall, very happy with my purchase, only wish the brain would have an internal pocket for things you don't expect to use but need to have (i.e. bandaids, moleskin, tampons, sunscreen). I don't like having that stuff flop around and get in my way while trying to reach more important things.

      Ah one last thing, I loved the outer hydration pack!!! I didn't refill much due to constant fresh water in Iceland, but when i did fill up, I used the Osprey bladder, which detaches from the tubing for easy in and out. Only complaint is that when your bag is full, it is almost as difficult to get into the outer sleeve as it is when it's internal. Maybe slightly easier, I'll have to play with it more to get a real gauge.

      Great backpack

      • Familiarity: I've used it several times

      I bought this pack for my sister. She is in love with it. She has taken it on small weekend trips and is planning on using it for some long thru hikes such as the Uinta Highline Trail and the JMT. Its super supportive and distributes the weight great. The pockets are in the perfect places and make reaching things in your pack super convenient. She also loves how the brain is removable and can be used as a small day hiking pack.

      Everything but the kitchen sink.

      • Familiarity: I've used it several times

      I took this on a two day backpacking trip, with my sister , who is in the market for a new backpacking pack. We both were very pleased with all the features. The pockets on the hip belt are so useful, as well as all the other pockets. They gave the pack a lot of extra space that you could fill, if you really needed to. I got all my gear in there which was extensive: stove, tent, sleeping bag, sleeping pad, clothes, toiletries. Plus, I had climbing shoes, a beach towel, and doggy necessity, which isn't normal for backpackers. Still, I had room for more.

      The hydration sleeve worked fine (hit me up for my favorite bladder picks). I just had to remember to put it in before repacking my bag. The front zip was really nice, and made it easy to locate items. And the zipper for the sleeping bag was quite handy. I misplaced my stuff sack, so I just stuffed the bag in the bag compartment and cinched it down tight. It worked great!

      I have a 17" torso, so I got the the small (hit me up if you don't know how to properly measure your torso). The straps are very adjustable, in the hips and shoulders. So, it works for me, but a medium would be better, so the straps aren't maxed-out, all the way. I like my packs to ride really heavy on my hips. My sister has an 18+ torso, so this size was not right for her.

      I'm was very happy with this pack. I only did 4 stars because I like Osprey's strap adjustment on the Viva 65 better. They were easier for me to use and adjust when we swapped packs, so I wish it was the same design on this one.

      Note: the Osprey Daylite will attach to this pack, for use on day hikes.

      Everything but the kitchen sink.

      Sweet, supportive pack!

      • Familiarity: I've used it once or twice and have initial impressions

      I bought this pack to use for some 3-5 day overnights, and I love the fit and color. Only thing I would add is a few more small pockets on the outsides for little supplies. It adjusts easily and is the perfect size for longer adventures. The removable top pocket is a very nice feature.

      • Familiarity: I've used it once or twice and have initial impressions

      I have yet to use this pack but I've used my girlfriend's so I'm confident that it's comfortable, functional, and super durable. I ordered a size Small and needed an XS hip belt so I got in contact with Osprey and they took care of me oh so well. I was able to swap them out without a problem. If you're looking for one of the most precise fits you can get in a pack along with a killer manufacture warranty, definitely go with Osprey. I plan to use my pack next weekend for a backpacking trip in Moab and can't wait to see how it holds up!

      Get sized!!!

      • Familiarity: I've used it once or twice and have initial impressions

      This is a great pack. I have the men's version of this pack (Aether 70) and I love it. My wife would love it too, except that we got a size or two too big. Well made pack, just do yourself a a favor and get sized. It's not a t-shirt.

      Hey Brad - Yes, please get sized. You can do it yourself at home. Get a measuring tape and do this:

      1) Get a friend to help.

      2 Find the crest of your hip bones by putting your thumbs in your armpits (bare with me here!) and drag your thumbs down the sides of your body until you hit the highest part of your hips, It's on the SIDE of your body, not the part of your hip that might poke out toward the front of your body.

      3) Take that point on the side of your body, and on the same plane (don't move up or down), slide your thumb to your spine. That is your bottom measuring point.

      4) At the base of your neck, find the bump that is your C-7 vertebrae. If its hard to locate, bend your head forward. but once identified, then stand up straight.

      5) now you have a top measuring point and a bottom measuring point. Once you get the measure done, then use that number in inches, and refer to the size chart located above!

      There is a great set of instructions on the Osprey website, so please go there if you have questions.

      rain rain go away

      • Familiarity: I've used it several times

      This is a great pack!

      -the hydration access is a must

      - took this backpacking in Olympic National Park for 4 days 3 nights

      -was able to fit all the gear I needed for the four days

      -the only thing this was missing was a rain fly which I needed basically my whole trip because it rained. Fortunately, one of my campmates had and extra one.

      rain rain go away

      Built for a woman's body

      • Familiarity: I've used it once or twice and have initial impressions

      I recently took this pack on a 3-night bakcpacking trip and fit everything I needed inside easily. I'm a heavy packer, to me it's no problem carrying extra weight to enjoy the finer things. Point being, this pack could be used for longer trips, I've had friends travel all over the world with this.

      Osprey's women packs have superb design, are fit to women's curves, and are well thought-out. From the pockets to the fit adjustments, this pack makes being in the backcountry a lot more convenient in every way.


      I am 5'7" and 130lbs with an average to short torso and the Small fit perfect, with room to adjust for a larger torso. The waist-belt fit comfortable around with plenty of room for adjustment too. And the waist-belt can be heat-molded, that's pretty awesome!

      For information on sizing and fitting your Osprey pack, check out this guide they have created:


      The top brain of the pack detaches and can be used as a daypack. I was able to fit my shell, a sweater, and two water bottles in it for a day hike (see pic below.)

      There is a sleeping bag compartment built into the pack located on the bottom with zipper access and internal straps to separate it from the body.

      The body has access from the top and front panel access (making it easy to quickly un-bury rain jackets accidentally packed in the bottom.)

      Water bottle pockets are located on each side with sleeves that have an option to hold bottles upright or sideways (making them easily accessible to grab when you're hiking.) Inside the sleeves there are a couple small straps giving you the option to secure smaller things you may want to carry here instead of water. This would be good to carry hiking poles or a fly-rod!

      There are two zippered waist-belt pockets for small hiking necessities: chapstick, snacks, sunscreen, phone, etc.

      There is an external hydration sleeve, but the pack does not come with a bladder.

      The outside stretch mesh pocket is great for packing maps or stuffing a layer in.

      There are multiple external straps to carry whatever else you may need. Great for strapping dirty shoes on with biners.

      This was a HUGE upgrade from my current pack, an older hand-me-down that doesn't fit my frame. Osprey makes great packs that are actually shaped to a woman's curves. This I seriously appreciated! I was noticeably less stiff after packing this around, making my whole trip more enjoyable!

      Built for a woman's body

      Hey Sierra! Thank you for the review! You know, Osprey keeps coming out with awesome product, but I tell you, I keep going back to my Ariel 65. Fits womens' bodies great. I am 5'4" and 150 (trying to get to 145!), stocky and strong, and it just becomes another part of me.

      Thanks again for writing!

      Love <3

        Love this backpack! Initially I ordered it in size medium which turned out to be a bit too big for me so I returned it for a small which fits perfectly. All of the compartments and pockets in the pack make it easy to fit more than I need for my backpacking trips. The detachable bag is super convenient for those shorter day hikes. Overall great bag, super comfortable and a must have for so many adventuring occasions!

        I luv this backpack!

        • Familiarity: I've used it once or twice and have initial impressions

        I bought an Osprey Ariel 65 because I was looking for something a bit larger than my Osprey Aura 50. As with the Aura, according to their chart my measurements would put me in a small or a medium; I a€™m right on the line. I ordered a small and it fits me much better than my Aura, which is a medium. I ordered the Deep Sea Blue which is a very pleasant color, not too bright. Material is very durable and pack well made. The wide hip belt has thick padding; I had no sore spots after carrying a 40 lb pack for several days. My favorite feature is a zippered sleeping bag compartment, with removable partition, at the bottom so I can wait till the last minute to compress and stash my down bag. Also appreciated is easy access to the main compartment through a large L shaped zipper that basically lays open the panel of the main compartment. It has loops on the top pocket where I attached my bear vault, but actually had room to pack it inside. The stretch mesh pocket is very handy and also the extra compression straps. The only thing I would change on this pack is to add a zippered pocket on the sides. I would definitely recommend this pack. It's a keeper! Happy Trails

        I luv this backpack!

        Fantastic Pack

        • Familiarity: I've put it through the wringer

        I have used this pack now for three years, have put hundreds of miles on it, and have lived out of it for about 6 straight months worth of time in the Sierra Nevada mountains. I have carried up to 60 pounds in it without an issue (no small feat for a 65 liter pack), and the pack is in as good of shape as the first time I bought it. Osprey might have a lifetime warranty, but there is a good chance you will get tired of the pack and end up replacing it long before you ever need to use it. Holds up to abrasion fantastically (I use it for mountaineering and carrying climbing gear as well).

        Handled the trek in and out of Havasupai

        • Familiarity: I've used it once or twice and have initial impressions

        Great backpack! I used this for a Havasupai trip this last spring. When we compared packs before the 12+ mile hike mine was much lighter even with all my gear for a 3 day trip. Didn't cause any rashes from rubbing and the hip strap was really comfortable. Has lots of space to hold a sleeping bag, tent or hammock and everything else you need for a couple day trip. I could of slept in this backpack the whole trip!

        Handled the trek in and out of Havasupai

        great bag

        • Familiarity: I've used it several times

        My first trip with the bag was a 4 day backpack to the Tonquin Valley, Jasper National Park, AB, Canada. Carried sleeping bag-clothing-climbing gear-camera gear in 25C summer weather. Excellent hip belt, very comfortable. Bag carries well with load of ca 45 lb (I am 5'8''), carried on 20km hike in to hut. Of course it's heavy! But it could be worse (with my old bag ;)).

        =Stable on back when walking over rough ground and full load. =Comfortable hip belt and shoulder straps.
        =Quite cool with the mesh system.
        =I like the separate compartment for water system (note- as others have said, load water first! otherwise hard to shove it in). =Lots of compression straps to attach extra stuff securely to pack. =Good ice axe loops.
        =Really like the zipper access to main compartment- this isn't useful when bag fully packed (too tight), but if bag half full, super easy to get into main compartment without undoing all the compression straps/top compartment.

        = Shoving the hydration bladder in a half full pack difficult. --
        =Should come with a rain cover for the cost of bag!!
        = I miss having a small inner pocket under the top lid (there are straps here used for taking bag off). This is normally where I secure small, important things like keys and wallet...
        =I like the stretchy panel on back of pack for shoving in jacket etc- however, this is only really effective if bag is not totally full. They should have made the fabric looser, so that there was more room to fit stuff when underlying fabric tight.

        great bag

        For trips across the world

        • Familiarity: I've put it through the wringer

        I've had an Ariel 65 since 2006 and have traveled from the U.S. to West China on trains, planes, and automobiles, and also by foot and it has held up with no broken seams or rips yet! One of the buckles broke though; at least that buckle is still half way functional.

        This has a inner pocket for a hydration pack, fits sleeping bag, clothes, tent, and has mesh side pockets for shoes or airing out dirty clothes, can even fit a fat nalgene water bottle in the side pocket!

        I went to a store and was fitted for a size small. My torso length is 17"

        So glad I chose this pack

        • Familiarity: I've put it through the wringer

        I shopped for a while trying to decide which pack was best for me for a 3 day backpacking trip. I chose this one and I'm so glad I did. I love the frame, the hip pockets, and the accessibility of this pack. The only thing that was a little frustrating was the location and accessibility of the bladder holder area. We packed our bags and didn't fill our bladders until we were on the trail so it was a really tight fit unless you take things out of your pack, put the bladder in, then put everything back, and who wants to do that. I could fit all my gear for 3 days but I know I could fit it for longer if I needed to. I almost went with the 75 but I'm glad I didn't 'cause I would have just carried more. All in all, a durable and extremely comfortable backpack. Once I had everything adjusted to the weight on my hips, I was set. My pack was about 35 lbs max, and I am 5'5" I got the size M.

        Unanswered Question

        Hi there!
        I just ordered the Osprey Packs Ariel 65 Backpack (size S Women's). I would like to order the rain cover and airport lockable zipper bag for my new pack. Please advise what size these items I would need for my Osprey Packs Ariel 65 Backpack (size S Women's).
        Thank you so much in advance.

        I'm interested in buying both a hiking backpack and a day pack. It mentions in the description that this item "doubles as a daypack", how does this work and do you recommend relying on this product to act as both?

        Bridget, thank for the question. You are definitely describing 2 different packs. Where the description says "doubles as a daypack", it's referring to the top lid that can turn into a waistpack for day outings.

        This pack is phenomenal as a backpacking pack - you cannot go wrong. But if you want to reach out to me about describing what activities that you would like to do with your day pack, I would be happy to recommend one for you.

        Thanks for writing!


        Osprey Rep

        Hi Leta,

        Thanks for clarifying! I'm heading to Madagascar for two years and I'd like to bring a hiking backpack (I think I'm definitely going to get this Osprey one), an overnight bag for shorter outreaches (but that's large enough to carry a few outfits/shoes/etc) and a smaller backpack for daily tasks (thinking maybe a hydration pack with some extra storage room would be best)..Do you have any specific items in mind that may work? Thanks for your help!!

        Hey I am 5'5 and i am 120 pounds but i am only 14 years old and i am worried if i get a small then i will grow out of it. Do you guys think i would be better off with a small or medium?


        The big determining factor for pack size (S, M or L) is going to be your torso measurement that goes from your iliac crest to your C7 vertebra. That measurement will correspond to the size you'd want. The Small for the Osprey Ariel 65 is going to be good for ladies that measure between 16 and 19 inches. At 5'4'' without measuring, I'd think you'd be closer to the 14.5-16" range for your torso measurement (depending on how you're proportioned).

        Shoot me an email anytime you have questions!

        I'm trying to decide between getting a small or a medium. I'm 5'7", 120/125 pounds with a slim build. Which should I go for?

        Best Answer

        You need to measure your torso from the nobby piece at the top of your shoulders down to the top of your hip bones. There are several Youtube videos to show you how to have a friend do it. Your overall height and weight don't determine your backpack size. It's not like buying a sweater. For example, I am 5'9" but am on the small end in backpacks because I have a 17" torso. So, I have a small Ariel 65. As for my width. You need to measure your waist around the top of your hipbones and compare it to the size chart. If you need a different hipbelt, you can buy one and swap out to hipbelt that comes with your pack.

        This is important!

        I doubt backcountry can do this for you, but if you ask through the chat service found at the top of this page by clicking the "live chat" link they can tell you for sure.

        If they can't I know that If you go into any local outdoor outfitter that carry's osprey packs they should easily be able to set you up with a pack that has a differently sized hip belt.
