    Osprey Atmos 50 Packis rated4.2105out of5by19.
    Rated4out of5byfromGreat Pack for TrekkingI am 5'10" 140 lbs and I ended up getting the large. I have a 32" waist, and can still get the pack cinched down enough, but the waist straps are nearly all the way cinched. It is VERY comfortable and rides well. I use the Osprey water bladder system in mine, and really like having that in there. Due to the airflow back panel, the interior of the pack has a bow to it, which can make getting some of the bulkier items into the pack a little difficult, but by getting a little creative where you put things, it still packs out very well. I can let out all the straps and load this thing down, or cinch it down tight and use it like a day pack. I bought mine in summer 2013 and have hiked a lot with it here in the states and in Nepal.

    Rated4out of5byfromComfortable, well fitting packI thought this was extremely comfortable, and with how adjustable it was, it was easy to make this fit comfortably each day no matter how many layers I was wearing or how much I had it loaded. My only con against it was that doing a winter overnighter hike naturally requires more gear. With all the straps and clips and hookups on this pack, I simply could not find a good location to clip up the sled of gear I was towing.

    Rated4out of5byfromDecent bag for the Camino de SantiagoI bought this specifically for use on the Camino de Santiago in September/ October 2013. I wore it many times while training prior to going on the trip. The pack is easily adjusted and very comfortable. I especially liked the waist belt. When it is properly packed, it really floats on your waist! Many have said it is hard to pack due to the rounded shape of the back, and I somewhat agree. It is a little bit awkward, but not so much that it is something to worry about. I used lightweight packing cubes, which I felt made it very easy to pack. My shoulders do not have a lot of mobility when reaching backward, so for me personally, it was hard to use the outer pockets on the sides of the pack (where most would keep their water bottles). There was more than enough room in my pack for this trip. Since I had a hard time reaching bottles on the side of my pack, I instead bought a bladder and put it in the top pocket behind my head. It worked like a charm, and was easier than using the dedicated water bladder pocket inside the pack. I added some small outer pockets to the straps for my camera, music, and snack. I also used lots of carabiners on the back to attach things like sandals, etc. I strapped my sleeping bag to the outside of the backpack instead of putting it inside the pack. Keep that in mind if you get a rain cover for this backpack! Overall, I thought this pack was great. I saw more of these packs on the Camino than any other brand/ style. Many (most?) people probably would not have the problem that I had reaching the back pockets, because I think that is just due to my quirky body. Try one on in the store and see how it works for you.

    Rated5out of5byfromHits the Sweet SpotI finally found the pack that works best for me. I have many packs, from a large capacity external framed pack to a minimalist pack that weighs about 1.5 pounds. I prefer the open air and back dryness of an external framed pack but until I got the Osprey Atmos 50 I could not find an internal framed pack that carried like an external. This pack is right-sized for 3-season multi-day excusions if you pack light (without going to extremes). I actually found it to be roomier than my 62 liter pack. The key to going with a pack of this size is to get a down sleeping bag and a small shelter. Together with a lightweight camp stove everything fits inside quite easily. Lots of room for clothes, food, water bladder, fiter, etc. Once you get down to this size and weight you won't go back. And this pack, although a little heavier than the lightest ultra light packs, puts its extra ounces to good use. The suspension easily carries loads to 35 - 40 pounds in comfort. Something that most ultra lights cannot do. Very good build quality and it is way more adjustable than anything else I have owned or used. I am 6'1" and weigh 175 pounds, and the large size fit me well (at its shortest setting). It has only one place to load from (the top) but I don't find that to be a significant inconvenience. The pack is small enough that you can get to anything you really need quite quickly. I have four good backpacks, but this is the one I will be using most often.

    Rated5out of5byfromGreat Intermediate Sized Pack!This is our second Osprey pack, and we continue to appreciate the quality of craftsmanship, attention to detail and lifetime warranty. With REI's help with proper sizing, this pack is a great fit (large) for a 6'+ frame. It's a perfect in-between pack, much more than just a day pack, but sufficient for a light weekend excursion,with plenty of external straps for added accessories. Plenty of storage, lots of padding in all of the right spots and easy access to all compartments. Only con: water bladder is a bit restricted with a full load, but this doesn't diminish an otherwise outstanding product!

    Rated5out of5byfromAn excellent pack for the Money!I use this pack on weekends to hike overnight in various areas of the State parks here in Washington. I've used it for no more than 3 days and nights. I like it a lot. The weight is light and I've packed as much as 45 lbs into it. I usually carry no more than 30, as I like to enjoy myself.

    Rated2out of5byfromOsprey 50. . . item not compatible with Camelback water carrier, as are previous models id'ing themselves as Osprey Atmos 50.
    Date published: 2013-09-28
    Rated5out of5byfromComfort from the StartI shopped several packs for a smaller version of larger one and settled on the Atmos 50 for an 8 day inn-to-inn hike via the Verdun transverse & gorge in Provence. Immediately comfortable but I am a minimalist - perfectly sized (only wish it had divided upper/lower compartments but realize smaller size - no straps for sleeping bag). It's a keeper for day and inn-to-inn hikes ...with thoughtful harness system for bladder feeder.
