One of the most rigorously designed packs on the market, the lightweight Osprey Atmos 50 sets a new standard in comfort for lightweight backpacking. Features: Top-loading design with a floating lid pocket allows extensive gear storage. Features twin front slash pockets with water-resistant welded zippers, stretch-woven front and side pockets and zippered mesh pockets on hipbelt. New easy path zippers make it simple to open the hipbelt pockets with one hand. Osprey AirSpeed suspension features an aluminum alloy frame and titanium torsion rods for support yet flexibility while carrying heavy loads. Anchoring to the lumbar area, the suspension provides uniform pressure with no hot spots. ErgoPull hipbelt closure provides extra leverage in cinching, drawing tension along top and bottom--not through the center--relieving hipbone pressure. Thermo-formed and perforated waffle-pattern shoulder straps and hipbelt save weight and enhance breathability. Hydration-compatible design features hydration tube portholes and uses cavity behind mesh backpanel to hold reservoir (sold separately). Daisy chain with removable shockcord clips let you attach a bungee cord for lashing on extra gear. Removable sleeping pad straps. Specifications for torso / waist and hips / base volume (cu. in. and liters) / weight are as follows: Small - 16-18.5 in. / 27-31 in. / 2,800 cu. in. (47 liters) / 2 lbs. 15 oz. Medium - 18-20.5 in. / 30-34 in. / 3,000 cu. in. (50 liters) / 3 lbs. 1 oz. Large - 20-22.5 in. / 33-37 in. / 3,200 cu. in. (53 liters) / 3 lbs. 3 oz. An oversize shipping charge of $10 is applied to large packs. This is on top of the regular shipping charge. Osprey packs

Light Hiking | |
| Rating: |  |
| The suspension is great and breaths very well. The 2009 design allows you to fit much more into the main compartment than any other breathable pack I have seen (significantly better than the 2008). The 2009 also has water bottle pockets that fit bottles diagonally so you can actually reach them (I used a 1.5 liter SIGG).They are just about as light as the Exos but are made of a more durable material. I especially love the stretchy mesh drying pocket and compression straps. I was surprised when comparing the Atmos 35, 50, and 65 because the main compartment on the 35 and 50 are almost the same size if you only pack to the top of the frame (I hate packs that stick up high). The 65 has additional space due to the zippered lower compartment. If you intend to use the pack for travel on a plane or want the flexibility to compress it down and have a great day bag – get the Atmos 35. Even the large size can be carried on any flight (except flights out of the UK – the large size was a few inches to long if they actually measure however I was able to get mine through security b/c it looks enough like a normal back pack). Also the zippered main pocket makes accessing the main compartment and things packed at the bottom much easier. If you know you will be hiking light, go with the 50. It has a brain and extra space above the frame if you need it. It does not have the lower pocket and will distribute the weight of lighter loads better. In addition if compressed, lacking the lower pocket will make it better for a day bag. If you are only using the pack for extended hiking and camping I would probably go with the 65 because I like the zippered lower pocket on the 65. | |

My favorite mid size pack | |
| Rating: | |
I have been using this pack for about a year now and personally I love the way these packs fit, they are very light and comfortable with tons of features. I sweat a lot in summer and although the design of this pack won't stop that (only cold weather can do that), it reduces it a lot! The only thing I can think of that I would like that this pack doesn't have is a daisy chain or more places to attach things to the back of the pack (and that is mainly because I use it for winter as well as 3 season). I have three packs, a multi day pack (which I got before I found Osprey packs and can't justify replacing), the Atmos 50 and 35. Each has their own place, I use the 35 for most hikes and the 50 for light overnights, winter day hikes (not what the pack is for, and although it works it isn't what I would recommend) and hikes where I want to bring something that takes a lot of space (for example I once took ice cream to the top of a mountain and I needed the space to fit the cooler with dry ice as well as the usual gear). This is usually overkill for light day hikes and it isn't large enough for multi day trips unless you are a real minimalist. You should go and try an Osprey pack at a local shop to make sure you like the feel, some people like the way that Gregory (or some other brand) packs fit better, but if you like the feel you will love this pack! | |

BEST ALL ROUND PACK I OWN | |
| Rating: | |
| I have 80L, 90L and multiple 25L and below backs and was looking to get a 35L and a 50-65L to finish off the group. Through reviews and recommendations from friends, I started off with Osprey's Atmos 50. Glad I did, I really don't need the 35L version now (although I'm sure it's still a good pack). All the other good points listed in other reviews are true, my personal highlights for pros are as follows: top note for the waste strap, doesn't look like much at first(worried actually) until I put it on, smooth and very good distribution on waste (no pinching) and takes weight well. The little details of pouches in waste strap and user friendly front compartments was well thought out. The airflow system works as advertised, I'm a natural born sweater and where this doesn't eliminate the problem, it does reduce the problem more than any other backpack I've tried or seen on the market, good call boys! Nothing else unique on the pack, has all the other basics expected on a higher end pack. One and only concern is the durability, the materials are very light and construction is good, I fear that these new generation of backpacks (other companies switching to similar materials) are more susceptible to tearing on a branch or other gear during the trip out, but only time will tell. So until that tear happens, this pack makes giving a 5 easy. If you're looking for a 25 - 65L pack, save the trouble of time and money and pick this one up. Cheers and enjoy! | |

Great pack! | |
| Rating: |  |
This backpack is one of the most comfortable packs that I've ever used. Its weight to volume ratio is great: 3 pounds for 50 litres (its pretty hard to beat that). The only concern I had with buying this pack initially was the fact it was so light I thought it might not be durable enough (don't worry, its very durable). This pack has held up great to all sorts of trouble that I've put it through. The only grip I have about it is the way the frame is built to create the ventilation chamber. It makes retrieving bulky things from the bottom of the pack difficult. It also makes carrying things like bear cans nearly impossible. Note: these grips wouldn't stop me from buying this pack again but this is the reason it didn't get a 5 star rating. The things I like: The hip belt pockets are great to keep snacks, maps and other little things necessary for quick access. The hip belt itself is very comfortable and distributes the pack weight evenly. This thing weighs simply nothing by itself (love that). The ventilation chamber is great for hot days (and can be packed with gear). There is also a cool pouch for a hydration bladder and two outside pockets for water bottles (nalgenes fit great in these). All in all this is a great backpack. I've had my pack seriously overloaded with winter gear and it still handled the load great! | |

| I did SO MUCH research before buying this, as it's my first pack and I live far away from camping stores. Out here on the Big Island of Hawaii it's great to have a pack that I can use for lightweight day pack adventuring, that keeps me dry, as well as for a few overnighters, camping or travelling without a problem. The red color is beautiful and shiney.I baby it a little...The zippers are alot tougher than I sometimes think they are, and the weight distribution is fantastic. I'm a five foot five female, weigh about 125 and love to jog and hike fast when I'm on the trail. I've gone down steep inclines, jogging, with this packed full, with an eight pound tent in it, and my back didn't hurt a bit, it's all distributed correctly. The numerous pocket options keeps me entertained, and I can disconnect the top compartment and put some little things in it if I don't want to carry the whole pack. It's also hydration compatable, can compress to a day pack or expand to what looks like and feels like more than the 3,000cu. I like the airflow back pocket for dirty clothes, or extra stuff, and the water bottle pockets are big enough to put other stuff in them too. Way cool pack, so glad I did the research and made this choice. Definately get the right SIZE tho. | |

Two thousand miles and counting | |

| This pack served me well on my 2007 Appalachian Trail thru-hike. I've always sweated a lot, but never once did I get a sticky back from the ventilated back on this pack. In freezing temperatures, I stuffed my fleece in the ventilation compartment. The design is ingenious and by far the best pack I've ever worn. Don't load it over 30 for a good ride. I once carried slightly over 35 lb between resupplies and the molded frame didn't quite fit right. A huge plus, the shape and movement of the pack really keep it out of the way when climbing is in order. The awesome Osprey staff even fixed my nearly worn out pack at Trail Days, so now it's going on a Florida Trail thru-hike once I'm done with grad school. For the Pacific Crest Trail, I'm upsizing to the Atmos 65 due to longer resupply stretches. My only possible criticism is the odd shape of the inner compartment that forms due to the ventilation compartment. It took me a month of trail before I learnt how to best fit all of my gear in there. In short, a truly great pack. My Osprey Atmos 50 has been through it all (and looks like it too), but still has another two thousand on it. | |

6'2" 230lbs large size | |
| Rating: | |
I have the above measurements and pack size. This pack has performed well for me. The only time I had a problem was day 2 of the Inca Trail. I didn't adjust the straps properly in the morning and one of the shoulder straps really dug in hard all day afterwards. I tried correcting it at lunchtime, but it was already sore at that point. Other than that, which is partially my fault, I've had no problems. I think the only minus is it's lacking the bottom zip the 65 has. I have the 08 and before version of this pack. Additionally be careful as 09 brings a new model with several additional features: - air cavity is vented on the side, this allows it to be smaller and gives you a easier load/unload. - has a quick stow and go system for storing trekking poles on the go (possibly other things). - the water bottle pockes on the side are angled so you don't have to remove the pack to get in/out of them with a little practice. If any of those features sound good to you, you might want to compare the money you save buying this model on sale vs. holding out for the newer version. | |

I used this pack size large on a 21 day trek in Nepal around Makalu I packed my down bag, Thermarest, sometimes the tent, snack food, chaco's,extra set of clothes, hygiene stuff,first aid, 100 oz. pladder, MSR filter, and other gear headlamp,knife, etc. If you are a serious about going light then this is the pack use compression sacks for everything u can and it will hold all you need. Even used it as my carry on the whole trip. As far as comfort on long hauls it is great. Began the 21 days with a 37lb. load sometimes 40lbs. when carried tent by the end had 35lbs. and was awesome no matter the load. I will add that even though you need a rain cover I got dumped on for about 2 hours before I stopped to dig my cover out (keep it handy) and only a few things got damp. Hip pockets are real handy, should have kept my cover in one. Only down side is loading and unloading. I would add a bottom load zip as well then I would call it near perfect. Use it all the time on short hikes in CO perfect. Osprey makes some tough packs this is my Favorite. | |

Comfortable and Lightweight | |
| Rating: | |
| I bought the Atmos 50 backpack for a day hike up Mt. Whitney. I wanted a lightweight pack large enough to hold rain gear, extra layers, water filter, survival gear, etc. This pack was plenty large enough to hold all my gear, weighing in at 15 to 22 pounds including 2-3 quarts of water and food. This pack is very comfortable. The shoulder and waist straps are easy to adjust, but I found the waist strap would occasionally loosen up a bit, thus requiring an occasional tug on the adjuster. My hiking buddy also experienced the slipping waist strap on his Atmos 50 pack too, so I wasn’t the only one experiencing this problem. The breathable mesh back panel is awesome and keeps the back of my shirt dry. My CamelBak water bladder works perfectly with this pack. I usually hang it behind the mesh back panel to free up more space in the main storage compartment. One of my favorite features is the zippered mesh pockets on the hip belt, which provides easy access storage for my camera. | |

I have this pack, but in the 65 L option, and I have been very pleased with my purchase. Some of the things that I enjoy about this back is how light it is. It weighs next to nothing. I also enjoy the ventilation mesh that rests up against your back so you don't sweat too much when you are hiking in the summer. Also, very roomy, I am able to carry all of the essentials and some. I was very pleased with the amount of pockets for extra gear outside of the main chamber. The hip pockets are great for things that require quick access (i.e. camera, knife, maps, or whatever you can think of that you would want quick access to). There are also many straps and clips for outside storage. The only downfall to this back is the frame system which takes away from the volume of the main chamber. Other than that this pack is fantastic. You will be pleased with the durability, comfort and versatility. | |

Sucks | |
| Rating: |  |
The stupid concave back part is made of rough material so unless you are wearing a decent layer it will rub a hole in your back. My back still sweats with this ruck too its just a waste of space The mouth of the ruck is way too small for a 50. With the retarder hump or whatever its called. its hard to pack it so it doesnt stick 3 feet off your back. It is not streamline. | |

Passable | |
| Rating: |  |
| This pack seems quite well thought out when it's not packed full of your gear for the weekend, but in practice, it falls a bit flat. The Good: There is a pocked stitched to the underside of the top pocket that's perfect for things like keys, phone, and wallet - things you probably won't need, but definitely need to keep track of. Also, an incredibly loud whistle is built into the cross-chest strap, which may or may not come in handy, but it's comforting to have immediately available. The Bad: First of all, when you pack this bag, the AirSpeed suspension/air circulation system that seemed like it was going to work so well flattens out and effectively disappears. The straps are redesigned for this year - sort of - they just feature bigger holes for ventilation. I didn't notice any real advantage, having used both this and the earlier model of pack. The hip-belt pockets are made of some material that reminds me of chicken-wire, and it's incredibly hard to open or close them one-handed. The Verdict: This pack is well suited for real lightweight minimalist campers that aren't terribly concerned with how comfortable their pack is on longer hikes. | |

I pride myself on being the most demanding of consumers. I think it helps others stay informed in an age where you cant always try things on. I find the sizing does not fit broad shoulders well, mostly because some of the plastic hardware would rest on my back when I carried the pack. Aside from that, the mesh panel allows great ventilation, but at a substantial cost in usable volume. The main compartment looks like a crescent shape when viewed from the side, tough for your longer items. Additionally, I shouldn't have to move up to the atmos 65 (which i liked less) in order to get a bottom zipper. | |

Good Enough | |

I've been trying to slowly convert all my gear over to packing lite. This years money went into buying a pack. At three pounds for 50 liters, the Atmos 50 was on a short list. Although big enough for my gear (I had extra room), I couldn't get the bear can to fit inside! I was prepared to attach the can externally, but there were only limited options for doing so. I like the way it fit, but left me a little sore. Also, maybe I'm just frivolous, but It would be nicer if it had an external pocket that was a little safer from precipitation. | |

Great pack, not great durability | |

| This pack is great, fits like a glove. (I have the Aether 70) I love it and everything about it except the fact that I question its durability. I've had this pack for 4 months now and the frame is already showing through the bottom fabric from setting the pack down with a load. It needs some kind of durable material to cover these parts because any abrasion or contact with a hard surface quickly eats away at the material covering the frame at the bottom of the pack. | |

Found out while training for a climb that the shoulder straps dug into my clavicles on both sides, and one of the rear struts dug into my back. Had to buy dense 2" foam and pack cloth and make new padded shoulder straps. Sewed them onto the existing straps with upholstery thread. The pack also did not feel very roomy inside as compared to its external size. I did like the small pockets on the waist strap. | |

Found out while training for a climb that the shoulder straps cut into my clavicles on both sides. Had to buy dense 2" foam padding and pack cloth to make padded straps that went from the top of the shoulder all the way to the bottom of the strap. Sewed them onto the existing shoulder straps with upholstery thread. Go figure. Otherwise it is a good pack, but doesn't feel very roomy for it's external size. | |
