Fit, function, and fantasticalness.

Osprey's Aura AG 50 Women's Backpack checks all the boxes. It fits perfectly, works well, and has just the right amount of gizmos and gadgets to keep you organized and happy without being confused or overwhelmed. It all starts with Osprey's Anti-Gravy Suspension, which uses a seamless panel of lightweight mesh that extends from the top of the back panel all the way to the hip belt, providing superior ventilation and a fit that's naturally contoured to your back. The upshot is effortless comfort and ventilation, so you can cover ground on multi-day trips without stressing about your pack.

The comfort of the Aura is boosted by the Fit-on-the-Fly hip belt, which allows seamless adjustment of the padded portion—not just the buckle straps—so it rides comfortably on all sorts of hips. Internal and external compression straps keep your load from bouncing around, and the removable lid pocket lets you size down if you're looking to travel light and quick. Osprey integrated a special sleeping bag compartment on the bottom of the Aura, included an internal reservoir sleeve, and finished the package off with a compressive FlapJacket back pocket that cinches your load down further and lets you tuck a layer away for easy access. We'd also be remiss not to mention the top and front-panel access points, which let you quickly and easily find gear no matter how deeply it's stashed away.

  • Anti-Gravity Suspension system
  • Heavy-duty nylon fabric
  • Top and front-panel access
  • Fit-on-the-Fly hip belt with pockets
  • Sleeping bag compartment
  • Removable top lid with pocket
  • FlapJacket back storage and compression panel
  • Reservoir sleeve

Older version better for Thru Hiking

  • Familiarity:I've used it several times

I had the older version of this pack and used it to thru hike the John Muir Trail and the Appalachian Trail, as well as a few multiday trips in between--and I LOVED it. The XS weighed in at 3 pounds and was the perfect weight to durability ratio.

When I finished the AT I sent the pack back to Osprey as it had some wear and tear and Osprey replaced it (Thankyou!) with this newer version.

I love the new colour and YES the suspension system is really quite impressive and comfortable. However, this new version is quite a bit heavier--3.10 pounds for the XS--not good for thru hikers who always keep on eye on weight.

In addition, the new features and materials are not an improvement ; the sleeping bag compartment is unnecessary and cumbersome--only adding weight--what’s wrong with stuffing your bag at the bottom of your pack anyway? --it’s the last thing you need at the end of the day; the extra lid cover which you are supposed to use in case you want to hike without the `brain` is also not needed--the side pockets that used to accompany the back pouch which where super handy are gone--and overall the material weights, such as the compression straps-- are heftier than needed--while the mesh material on the back pouch isn`t durable enough (Mine punctured a hole on my first overnight trip with it). Finally –and this is a feature on most Osprey packs that experienced hikers hardly ever use—the internal reservoir sleave —Thru hikers don’t use this feature because, 1, you risk puncturing the bladder or not sealing it properly and saturating all your gear inside the pack—which is dangerous in cool/cold conditions—2., it’s a hassle to unpack your bag to retrieve the water bladder every time you come to a water source---thru hikers filter water 2-6 times a day—(to avoid carrying more than they have to) and can’t be bothered with packing/unpacking. I usually rig a Platypus Big Sip to sit in the back pouch so its easily accessible—and many hikers are starting to do this.

So-- I`m mourning what was in my opinion, the perfect backpack for women thru hikers who wanted the features and suspension system of a superlight pack—It’s too bad Osprey doesn’t make a version of its EXOS ultra-light packs specifically for women—

Final Verdict—I’m going to try this out on my PCT thru hike this year—but I’ll be taking my scissors to it and cutting off the features I don’t need to save weight—the sleeping bag compartment divider—and the second lid will be the first things to go!

I still Love Osprey packs and think they are the best on the market for women--but they missed the mark on this redesign !
I would however, recommend this pack to backpackers for weekend-to weeklong trips or if you are carrying 30+ pounds of gear.

Unanswered Question

Is this carry-on size or is it too big?

What are the dimensions when everything is compressed? Especially minimum height? I'm looking to be able to get a bag I can use as a carry-on (airline recommends ~22x16x9 inches), even if it means initially underfilling it on my there, and checking it on the way back home when I am carrying more. Thanks in advance!

Hey there - Leta from Osprey here. This will not compress in length. Depending on your size of frame, you are lookng at at or around 30" top to bottom. Again, the length cannot compress, just the width around. Hope that helps!



Great pack

  • Familiarity:I've used it several times

My wife used this pack on a 2 night camping/hiking trip to the summit of Mt. Whitney. It performed admirably. She carried about 25 pounds and was comfortable for the whole trip. The suspension seems to live up to all of the hype.



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

Used this for my first time backpacking Europe, for 25 days. It was the perfect size and fit everything I wanted to bring! I love the separate top and bottom compartments, and the zippers on the hip strap are great for small items you want to be able to find easily. My bag weighed about 23 lbs with everything in it and it felt great on! The hip strap really helped to take the weight off of my shoulders, as well as the suspension. Overall more than happy with my purchase.


fantasticalness is right on point

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

if you've never felt Osprey's AG tech--get to your nearest store to try it on. It's a game changer. The 50 has less bells and whistles than the 65 (no additional side-zip pockets or sleeping pad straps) but that was no love-loss for me. I opted for the 50 so that I would be forced to pack less. Still rebounding from knee surgery I wanted to ensure I could regularly keep my pack about 30lbs and I felt this was the way to do it. This pack still has a ton of features and the ability to pack down and stay secure--at no time have I felt like the space between my back and the pack (caused by the suspension system) alters my center of gravity and makes me less stable. This pack is everything and then some. Well worth the price tag especially with Osprey's lifetime warranty.

Does this pack INCLUDE a rain cover? Or is it just available for purchase?

Hey Matthew,

This does not come with a rain cover, this is one of the few Osprey packs that does not.

Shoot me an email anytime you have questions!

I just received the one I ordered for my wife and it did NOT come with a rain cover.

REI sells them with rain covers. I think they may be one of the few stores that provides the rain cover for this pack.
