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.

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

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 don't want a pack that makes contact with your buttocks. The pack feels featherweight when on my back.



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.

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.

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.

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.

Good product


I bought this pack for a 2 week trip to Switzerland. I carried it everyday as a daypack for my family with jackets, rainwear, water, snacks 2 cameras, several lenses (guessing 25-30#) I'm 5'9 and on the short side of 50. AG Anti gravity-Osprey didn't beat this basic physics concept but I have to say carrying this pack all day was not bad at all. I've carried several different packs and this one has a lot going for it. The waist belt takes some getting used to, it doesn't stay open, you'll learn to anticipate this when putting it on. The top flap for you minimalist (Osprey installed a top flap when the top compartment is removed) was a hinderance to say the least thisreally tried my patience, it always seemed to be in the way but a long way from a deal breaker. I too used this pack as a carry-on for the entire trip Columbia MO to Zurich I believe Osprey nailed the load suspension, it carries well and adjustability is off the charts. I was able to carry this comfortably for technical day hikes in the Alps with a tight fit to the opposite for walks in the city. This is worth the money!



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 :)
