    Takes trekking to a whole new comfort and support level.

    Solve your backpacking discomfort and hot spot issues with the Osprey Women's Ariel 75 Backpack. Designed specifically to fit a woman's body, the lightweight Ariel 75 has more than enough room to carry your gear for a week-long trip into Glacier or Yosemite National Park. Its AirScape back panel provides comfort and durability during intense hikes up steep terrain during warm weather, while its customizable IsoForm CM hip-belt supplies optimal load carry, support, and comfort.

    • Women's IsoForm CM hip belt balances firmness and cushioning for optimal carry while the IsoForm harness provides a women-specific, comfortable fit
    • LightWire peripheral frame effectively transfers load weight to the hip belt while the Airscape back panel features a smooth spacer mesh lumbar fabric for breathability and comfort
    • Single 6061-T6 center stay maintains back panel shape
    • Women-specific pack design features a narrow pack shape with added depth in the right places
    • Women-specific shoulder harness consists of thoughtful angle changes and varying padding thickness to create an anatomical fit for a woman's neck, shoulders, and chest while a sternum strap equalizes the pressure across the shoulder harness
    • Women-specific hip-belt takes into account that a women's hips are more conically shaped with a larger difference between the waist and hip measurements so you have a more comfortable load transfer and optimal support
    • Ariel 75 comfortably carries a maximum weight of 60 pounds for long weekend trips or week-long backpacking adventures
    • Large top opening lets you effectively pack your gear while a front J-zip provides quick access to the main compartment during your hike

    Daughter Loves

      She says this is the most comfortable pack she has ever had and used! And she knows her stuff! She has been a traveler for years and backpacking for many more. She 5'3", medium frame and chose the size small and fit her perfectly. I bought this as a gift for her and I'm glad it worked out. I want one!

      Great Backpack

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

      I brought this pack for the use of an upcoming two month backpacking trip in Europe but have used it for a few small camping trips. It is so comfortable!!! The design is amazing and your shoulders carry none of the weight! The backpack can compress to however small you want so I recommend going with this bigger size. I am 5' 8" and am size small, but highly recommend you go and get sized before purchasing.

      Easier than falling off...

      Just teasing, I didn't fall off of the log. Probably because the Ariel 75 handles a load so nicely.

      Curse cell phone videos! In my memory, this tiny creek was a yawning chasm.

      Hey Erin - great title. The Ariel 75 is my pack too, and when I am out with my family (and carrying more than I should!), I tack on the Osprey Daylite, a great add on to this pack, and a fantastic stand alone day pack!

      Thank you for taking the time to write!

      Hunting Goats in the Chugach Mountains

      • Familiarity: I've used it several times

      Cristine and her husband traveled to Alaska with her new Ariel 75 and she had some great feedback to share:

      "I just used my new Ariel Osprey for the first time on a 6-day backpacking trip in the Chugach Mountains in Alaska. My husband and I were hunting mountain goats, so this is pretty tough and rugged country. Our outfitter recommended all Kuiu gear because it is rugged, tough material that can withstand this terrain and conditions. After some research to find a pack that would best fit my female body frame, I chose the Osprey instead.

      Pros: This backpack is light weight. It fit my body frame perfect which meant no back or hip pain. I was able to climb for 4-10 hours a day with 35 pounds comfortably.The hip belt pockets were perfect for quick access items like a camera and personal items.

      Cons: The hip belt buckle broke! The top end plastic broke, but still held for the remainder of my trip.

      Conclusion: I love this pack! I have used several others through the years, but found this pack to be durable (aside from the buckle breakage), comfortable, form-fitting, easily accessible without the extras that increase weight, and the material was rugged enough to withstand the Chugach!"

      Osprey has the best warranty out there, The All Mighty Guarantee, so Cristine will be able to get her buckle fixed in no time.

      Feel free to contact me with any questions about Osprey Packs:


      Hunting Goats in the Chugach Mountains

      Hey Kyle, Thank you for sharing this. You are right on about Osprey's All Mighty Guaranty - we will take care of Cristine and her buckle as soon as we hear from her! But.... did you know that this pack (and the Aether, Xenith and Xena) have a second buckle included, in the event that something happens?? The second buckle is part of the top lid that turns into a waist pack. Just remove that buckle, and thread it through the main strap. Voila!

      Thanks again,

      47lbs - Yikes!

      Took the folks backpacking and we ate like kings! Which explains why my pack was 10lbs lighter when we got home.

      The Ariel 75 handled the load well and was exceedingly comfortable.

      The Kimber dog is spoiled, the large blue bundle under the headpack is her sleeping bag. It's really nice to be able to carry so much between the pack closure and the headpack - there are 4 different web straps to really suck everything down and make a nice, taut load.

      I've been drooling over the new AntiGravity Ospreys - they look and feel awesome - but I can't justify a new pack when the Ariel 75 is such a comfortable workhorse.

      47lbs - Yikes!

      Perfect Pack

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

      I used this pack to hike Rim to Rim at the Grand Canyon. Pack fit perfectly. Plenty of room for my tent, sleeping bag/pad, clothes and all of my gear. Carried 35# with no chaffing or discomfort. Hydration system is easy to fill. Can't wait to use it again this summer when I do the 100 Mile Maine Wilderness.


      • Familiarity: I've put it through the wringer

      I personally love Osprey packs in general because of how adjustable they are, so when I needed a larger bag for 5-10 day trips I went with the Ariel. It's great because I can pack it to the brim with food and gear when I need it, but I can also synch it down to fit 40 liters of gear without it loading awkwardly or having huge gaps. I also have some odds and ends in my gear systems (ice axe, backpacker guitar, etc.) so I love the number of straps that the Ariel comes with and how customizable it makes the pack. Additionally, it holds loads well and remains comfortable when weighted. Obviously it's not the lightest weight pack on the market but it's super durable and adjustable which makes it a great all-around pack for both front and back country.

      Even Better in 2013

      • Familiarity: I've put it through the wringer

      I bought an Ariel 75 in 2012 and I see that Osprey has addressed 2 of the 3 complaints I have about my pack with their 2013 update.

      1. My pack has an internal hydration sleeve which makes refilling the reservoir a pain - External hydration on the 2013.

      2. My pack doesn't have the snazzy 2013 hipbelt pockets. I have to choose pants/shorts carefully in order to have access to my cell phone while hiking. Not that I'm taking lots of calls while hiking, I use it as a camera and GPS.

      3. The top pocket is a daypack - love the IDEA loathe the execution. Look, they're calling it a lumbar pack but we all know it's a fanny pack *shudder* no one likes a fanny pack. It would be a lot more handy if the hydration sleeve and the daypack were married together - maybe in the next version.

      I know I began with a list of complaints but I LOVE THIS PACK. The hipbelt is gloriously comfy and I could wax on about it for a long while. I'm 5' and currently 130lbs but I've used this pack at 175lbs and it's comfortable at both weights (size Small).

      The hardware on Osprey packs is always impressive; everything from the buckles to the zipper pulls feels high-quality. The stretchy fabric Osprey uses on the front & side pockets is amazingly tough and stretchy - you can cram those pockets full.

      I have a second (discontinued) Osprey pack from 2005 that still looks brand new despite heavy use. I can't say enough good things about the brand. The Ariel 75 is a well-considered, full-featured pack that seems to have gotten better with age.

      does this pack come with a waterproof covering (down on the bottom)?

      Does this bag come with a rain cover?

      Can u get the different size in hip belt...

      Can u get the different size in hip belt to rest of pack?
