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

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 5 out of 5 by from Most comfortable pack in 50 years This is the most comfortable backpack I have owned in 50 years I have tried 8 packs in the last 10 years and by far the osprey AG 50 is the most comfortable. It would be nice to have an option with a lighter material to cut a little weight

Rated 5 out of 5 by from Featherweight I'm very satisfied with the Atmos 50. The frame is designed so the pack curves away from the back and has a very strong mesh allowing air flow. It also sits above the hips....you don't want a pack that makes contact with your buttocks. The pack feels featherweight when on my back.

Rated 5 out of 5 by from This has been serving me great! I have been using it on several hiking trips from 3 days to 28 day. It has been serving me quite well as a field instructor working with a crew. The only constructive I can find for this pack is that the zero gravity feature does not work well when the pack is fully loaded. That being said I love this pack, I have plenty of places to tuck gear and is pretty easy to keep balanced even when fully packed.

Rated 5 out of 5 by from Awesome pack. AG system is best I've ever used As an adventure guide I tend to put gear through a range of conditions and uses. I also end up carrying more than my "fair share" of weight. The Atmos AG handled anything I stuffed in it. The AG system spread the load out incredibly well and was hands-down the most breathable harness system I've ever used. Super comfortable. Totally sold on this pack.

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 4 out of 5 by from Great customer service! I was improperly sized and bought a large (i'm 5'7, 30 waist and 38 chest), big mistake. I went on a week long backpacking trip on the Georgia AT and carried all my stuff very well, I didn't think the large was uncomfortable until a past thru hiker started freaking out. Turns out the bag was waaaaay to big for me and I was carrying all the weight on my shoulders (so thats why I was so slow, hmph). When I got back I wrote the company and got a response within the day saying that they were sorry that I was sized wrong (not their fault) and that if I packed the box up and shipped it back (with a comp'ed return tag), they'd send me a new one in a medium. That was back in June, just haven't had the chance to write up. Other than the great customer service, the pack was great! Good ventilation on the mesh insured I was never sweaty on my back, the way the frame is though made it a bit difficult to load when synched up. It held up great, straps were nice, the hip belts pockets could be better but eh. The water bottle holder saved me from having to take my pack off so many times because of the way it is diagonal to the pack. THE BIGGEST CON: no sleeping pad straps on the 50, but they're there on the 65, whats up with that Osprey? The video is more or less to show you what it looks like and what went into the pack.

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!

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

• 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 chart above to find your ideal size.
• If you are in between sizes, it is ideal to try them both on before ordering.

• 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 Hipbelt size info above to help determine your ideal pack size, but again, your torso length is what should determine your pack size, NOT the hipbelt.

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.
