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.

Products on Sale are Discontinued Styles or Colors.

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 Osprey Atmos AG pack This is the best designed backpack of all. My grandson also said that it is so comfortable to wear. He can't wait to try it out on his next 40 mile hiking trip.

Rated 4 out of 5 by from Well made pack. Anti-gravity system rules! This and is an extremely well made pack, and the Osprey anti-gravity system is the best I've ever tried. The only fault with this pack is the lack of ties on the bottom for sleeping bag roll. I plan to use an inflatable, so that wasn't a deal breaker for me. That,and the price, are the only cons. Over all a very nice pack.

Rated 5 out of 5 by from Pleased grandson I bought this for my grandson who is going to Europe with his dad. Although he has not used it yet, they both agree it has the features needed for packing for the airplane, train and car ride.

Rated 5 out of 5 by from Great pack The AG systems make the pack feel much lighter than it actually is. The pack works great for section hiking and will hold what you need. Moosejaw made order it easy and they shipped quickly!

Rated 5 out of 5 by from Started me on Osprey This pack got me started on Osprey packs and I'll never look anywhere else. Every time I load it up I'm surprised at how much I can carry without feeling burdened or weighed down. It's a bit more complicated than a regular backpack and It does NEED* to be adjusted and sized properly but once it is and you have the proper distribution of weight into your pelvis it's an amazing pack. The anti-gravity system and really all of Osprey's packs with the mesh air flow areas are a godsend. I live in Hong Kong where you can pour sweat just waiting for the bus sometimes and regular backpacks just soak through immediately. The mesh suspension systems eliminate that problem completely. I do wish there was a bit more for organisation in the top compartment. Some dividers would help a lot as the main difficulty I have is how much things tend to bounce around and shift so I can't find the things I need while other things are falling out. The belt pocket zippers are a bit tricky but this can be a good thing in cities, especially on my little talon 22, you can store things in them without fear of pickpockets easily accessing them.

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

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.

- + 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.
