Product Description Item No.   10270402

The Osprey Atmos 50 AG Pack is a four pound pack for backpacking and thru-hiking your way through the wilderness. AG = Anti-Gravity, originally born in 1993, but 2015 provides a new take on the system with 3D contoured suspension, allowing you to move and wear the pack, all while feeling as if it isn't even on. Sounds like some real spacey, high-tech stuff. The mesh and die cut foam at the harness with the Fit-on-the-Fly™ hipbelt only adds to the comfy carry. The rest of the pack is all about convenient features for carrying your gear, from the removable floating top lid (with two zippered stash pockets on it) to the zippered sleeping bag compartment at the lower section. Compression straps cinch the load in for stability and an internal reservoir sleeve provides a handy spot for hands-free hydration. Last but not least, throw your camera and your favorite snack into the zippered hipbelt pockets and off you go to the next camp.

FEATURES of the Osprey Atmos 50 AG Pack

  • Floating, extendable top lid can be removed to save weight
  • FlapJacket provides compression and protection for the main pack when the lid is removed
  • Dual ice tool loops

Osprey Anti-Gravity

Osprey Anti-Gravity
Using Osprey's peripheral suspension design this lightweight, body contouring, three dimensional suspension literally allows the wearer to move as if they don’t have a pack on. Seamless suspended mesh from the shoulder blades to the lumbar and even into the hipbelt region disperses and balances the load like nothing ever has before.

Osprey Peripheral Frame

Osprey Peripheral Frame
Peripheral frame was a departure from the norm many years ago and it’s still the foundation of our gear hauling packs. A wire frame runs along the outside of the backpanel directly connecting the upper load lifters and the central core of the pack to the hipbelt to transition and spread the load. Allowing natural torsional movement, effective adjustable torsos, and different load range and backpanel builds makes this suspension design truly innovative.

Rated 3 out of 5 by from Fantastic bagpack, but why differences in features? I bought this backpack to find an optimum size and fit to go for overnight hikes while walking at a good speed to get a good workout. I've got the Aether 70l which is an overall great pack for multiple nights. For one night though a bit too big. Below 40 turned out to be too minimalistic for me, so 50 seems just right and the suspention system is fantastic if you want to move fast and you become really hot. What really is disappointing about this pack is the differences in features from 50 to 60 litres? Why would Osprey chose to do that? With a pack this size and load capacity you still have the same requirements for carrying an isolation sleeping pad when it's cold and you'd want the access to your stuff from the side zippers. I don't understand why you'd think customers using this bag with 50l have different needs than customers carrying 65l in this particular aspect. I'm actually thinking about returning this pack just because of that.

Rated 5 out of 5 by from Backpacked Europe Backpacked Europe for 51 days summer of 2016. Pack was the perfect size! We flew American Airlines to and from Dublin- we were able to use our bag as our carry on - no problems or questions. Stuffed full as 51 days is a long time! Flew smaller airlines between countries in Europe- still no problems using as a carry on! Quick to pack since we used packing cubes. Due to the awesome back support it is a little funky shaped along the back- but no difficulties with it. Can't wait to start using it on weekend adventures :)

Rated 5 out of 5 by from You won't be disappointed This bag is great - I am an avid hiker but hadn't gone on multi-day backpacking before. I used it days after my purchase for a 2 night, 3 day backpacking loop in Virginia in September - let me just say.... the back mesh really is the most comfortable bag I've tried. The pockets on the hip belt are wonderful - kept my phone and camera in each. I loved how it was easy to adjust even after getting it on your shoulders. I guess my only gripe is that I did experience a little bit of soreness around the hip flexors by day 2 - but I think this is inevitable with any bag as a lot of the weight is being distributed here. Regardless, it's a great bag, very comfortable, and you won't be disappointed.

Rated 5 out of 5 by from I love this pack ! I love this pack . I have had it almost a year and it was well worth the money. One thing that I like that many packs do not have is the ventilation on your back. it keeps you cool in the simmer.

Rated 2 out of 5 by from Be sure to get the right size. Be sure to get properly sized from a competent Osprey dealer or you will be stuck with a painful pack. There's little-to-no overlap with this pack if you're in between sizes or if the dealer you go to has no clue how to measure you. The dealer out went to just slapped in Osprey size chart on me and said you're between medium and large I would pick a large. The Torso length was 2 inches too long and the hip straps barely fit. I used it for a couple weeks before I found out how bad of a fit I had now I cannot return it back to the store. I just wish I had something that fits.

Rated 3 out of 5 by from this is not the one for me Looks great. Has all the bells and whistles minus a rain cover. A bit hefty. I am slim so when I adjusted the hip belt It was as far in as it could and just felt like it needed to be tighter. The hip belt is so bulky that when walking up stairs for example it wouldn't allow me to take a big step up without it restricting my forward leg motion. the crease in the hip belt were the black fabric meets the grey mesh was digging into my hip the whole 45 mile hike. It was not a comfortable pack that I was hoping for.

Rated 3 out of 5 by from Great bag but could be better This is my very first Osprey and I wanted to like it a lot but after several trips, there were some issues that I couldn't live with. I'm 5'5" athletic built (Triathlete, Wrestler, MMA, etc), ended up getting a small which is only 47L. Pros: Light weight, tough material, cool style, overall great quality bag. Cons: No sleeping bag strap(they should explain why), the hip straps tends to flex in all the time, you have to really work at prying it open. Anti Gravity hip area kept pushing my pants down. If you're a minimalist this bag would be great. Having 2 or 3liters more would've been perfect for my size and what I needed to bring. 47L really forces you to think and adjust your gears. I had to re-buy several items to meet this bag's request. If you need more volume, get the Atmos 65, that has more room and two sleeping pad straps in front of the sleeping bag compartment. Or get the Aether 60, that too has pad straps. Or you can jerry rig it like me and use the ice pick loop and attach strap buckles to it.

Rated 5 out of 5 by from So Far, So Good I purchased this pack a little less than a month ago, and finally had a chance to take it on a short trip last weekend. I loaded it up with gear, food, water, and some extra goodies just to see how comfortable it will be walking with heavy loads (my eventual plan is to use this pack on an AT through Hike). I only hiked a total of about 11 miles, but the pack was very comfortable. The suspension system offers a noticeably more comfortable carry, maintaining the majority of the load comfortably on the hips. I only wish that this 50 liter pack had the extra straps for tent or sleeping pad that the 65 liter has. Otherwise, features seem to be the same. It's just a matter of how much you want/need to carry. I did lash some fire wood onto the outside, as collecting wood was not allowed in the park and my friends and I were determined to have a fire, and the load was still manageable. Probably totaled between 50-60 lbs. I'm 6'5" and thin, and this pack fits great (medium size for me, as I am mostly legs).

Are the ones sold here (specifically size medium) the new 2017 stock with the SILVER osprey logo or older stock with the black & red osprey logo on the lid?

Asked by: feelgood13
Hiya feelgood13, thanks for your question! We currently have the black, red and grey logo version. We will get the new version after Osprey's stock is depleted. The only difference is the logo. Hope this helps!

OSPREY MEASUREMENT GUIDE

Please note that the info provided above refers to the torso size each pack will fit, and NOT any dimensions of the pack. Below are some steps for how to get your torso length. You should probably have someone help take this measurement for you so it is accurate. And they might accidentally touch your butt.

HOW TO MEASURE TORSO LENGTH:
• Start at the iliac crest, which is the top of the hipbones on the side of your body. These act like a shelf for supporting a pack hipbelt.
• From this level on your spine, measure to the C7 vertebrae, the knobby bone at the base of your neck when you put your head down.
• Make sure you keep your back as straight as possible while measuring.
• This torso measurement determines what size Osprey pack you should carry. Refer to the size charts above to find your ideal size.
• If you are in between sizes, it is ideal to try them both on before ordering.

HOW TO MEASURE HIPBELT SIZE:
• Measure around your hips at your iliac crest, NOT your waist.
• A properly fitted hipbelt rides centered over the hipbones and needs to be very snug.
• The padded portion should wrap well around your hips, leaving a gap of 3 to 6 inches between the tips of the both hip pads when securely tightened.
• Refer to the Hipbelts size chart above to help determine your ideal Osprey pack size, but again, your torso length is what should determine your pack size, NOT the hipbelt.

- + Warranty Info

ALL MIGHTY GUARANTEE - Osprey's Lifetime Warranty

When Osprey celebrated their 35th anniversary in 2009 they launched The Osprey All Mighty Guarantee. What that means to you is ANY Osprey product purchased at ANY time is covered. Any product, any reason, any era - the all encompassing Osprey lifetime warranty ensures their dedication to superior design, craftsmanship and quality of their products is backed up by their actions to replace or repair a pack so it lasts a lifetime. Or two.

Here are some details.... Osprey will repair for any reason, free of charge, any damage or defect in their products, whether it was purchased back in 1974, or ordered right now from this site. If they are unable to perform a functional repair on your pack, they will happily replace it. Osprey proudly stands behind the All Mighty Guarantee, so much so that it bears the signature of company founder and head designer, Mike Pfotenhauer.

Some Osprey All Mighty Guarantee FAQs:

What do I do if my Osprey pack needs to be repaired?
If you live in the United States and need a repair done on your Osprey pack, you will first need to obtain a Return Authorization number. You can do this by reaching their Returns Department at 866-314-3130, or using the information that is provided with a new Osprey pack.

What do I do if I just need a replacement pack part like a buckle?
Give Osprey a call at 866-314-3130 and they will take care of you.

How long will it take?
You can tell Osprey you need the pack returned by a certain date when you request a Return Authorization number, and they will do their absolute best to meet that deadline.

What if my pack is super dirty and stinks?
Clean it before you send it to Osprey to get repaired. The real reason is that there is a law that says if your gear is too dirty or odiferous (smelly), Osprey is not allowed to repair it and will just return it to you.

Do I have to pay for shipping?
A little bit. You are responsible for the cost of shipping the pack to Osprey, and they will pay shipping to return the pack via UPS or FedEx. Osprey cannot be held responsible if packages get lost in transit, so make sure you get a tracking number when you ship your pack out. Also, if you use expedited shipping be sure to let Osprey know (866-314-3130). They, in turn, will give your pack priority processing and return it using a similar expedited shipping method.

Do I have to register my pack to take advantage of this incredible guarantee, and/or need to be the original owner of my Osprey pack?
No! Osprey's All Mighty Guarantee is truly ALL MIGHTY. If you own an Osprey pack that needs to be repaired they will repair or replace it.

JUST A HEADS UP: If your Osprey product is not repairable and is replaced, the original product will not be returned to you. They will try really really hard to repair your pack, but if they are unable to make a functional repair, they will replace it. For products that are no longer in production you will be contacted by Osprey to discuss replacement options.

All good answers. So what is NOT covered?
• Osprey program packs or any Osprey pack used by outdoor programs are ONLY covered under Osprey's Program Pack Warranty, NOT AMG.
• Size and/or fit issues. Make sure you buy a pack that fits. Check out the size guide on Osprey product pages for more info.
• Personal preferences like colors you don't like, style of the pack, or not enough/too much room in your pack. Check the product description, features, specifications, and size guide to make sure you are ordering the right pack for you.
• Third party Repairs or replacements. Send your Osprey pack to Osprey and Osprey only to get fixed. Easy as that. And don't try fixing things yourself.
• Cosmetic wear and tear including any reasonable aging of your pack that affects only the appearance and not the function of your pack. Be proud of those scars!
• B.A.M.G. (Before All Mighty Guarantee) Repair Work. The All Mighty Guarantee applies only to repairs requested on or after January 1, 2009.
• A Osprey Hydraulics reservoir is covered by a limited 1-year warranty, which is the reasonable lifespan of a reservoir. Pouring and storing of warm/hot or boiling water in your reservoir WILL VOID your warranty, so don't do that. Reservoirs are NOT designed to contain or handle liquids at temperature.
