Description

Like wings for your back.

A super lightweight AirSpeed suspension system on the Osprey Exos 46 Backpack helps make this quick hiker a speed demon on the trail. It also may have something to do with the Exos 46's shelf full of industry and editor's choice awards.
  • Modified AirSpeed suspension combines the rigidity of aluminum stays with a tensioned mesh back panel for effective load transfer and cross ventilation
  • Ergonomic BioStretch hip-belt and shoulder straps ensure your load rests where it should for max efficiency
  • Removable floating lid lets you ditch extra weight for summit bids and fast-packing
  • Unique over-skirt compression strap extends from the front stretch pocket to carry bulky gear
  • Hydration sleeve holds your reservoir (sold separately) and H20 icons help route your tube
  • Stow-on-the-go trekking pole attachment lets you stash them without removing the pack

The size of overhead bins vary from aircraft to aircraft and of course it depends on how loaded up you have the pack, but generally yes, for most flights on 737/A320 or larger planes you'll be safe.

I just got my pack and I decided to take it for a test. Wow, did this ever pass with flying colors! I went for the weekend to Haunted Canyon in the Superstition wilderness in Arizona. My total pack weight was 27.5 lbs. (Because water and a bottle of nice scotch added 7-8 lbs of it).
From thee start of the hike it felt great. Everything compressed to a nice little bundle. Further into the hike I was climbing through a lot of rocky terrain and scree and pack stayed very secure, no movement at all. The best part is that as I was climbing so was the temperature. It was in the low 90's and I was on the sunny side of the mountain. I was amazed with the air flow on my back. I think because my back was protected from the sun and the airflow was so good, my back was the coolest part of my body.
Easy to hang water bladder in, Nice place to put hiking poles. My Gregory Baltoro has a place to put your poles that are more out of the way but reaching them and putting them on is not easily achieved while hiking.
One of the others I was hiking with had stuffed 45 lbs. of stuff in a Exos 58(For two people). I helped carry pack for a few miles and it is easy to tell right away that these are not meant for overloading. The air suspension was flattened out(No more airflow. Pressure on the shoulders. Even at that it performed ok.

Perfect  weekend pack!

I ordered this pack and so far i love it, plenty of room for a 46. I dont see how anyone would need much more room unless living out in the woods without resupplying for 2 weeks..

I'm impressed with what others said about Exos. It is what I'm looking for and I need users or specialist staff/ not sale person advise. I am small 5'03", 125 Lbs . 67 years old but love backpacking. Which size of Osprey Exos I should take. I am so confused the size chart (S:torso 18.5 in , hip 31 in and M: torso 18-20-5 in, hip 27-31 in) Which one is really small ? and I really need a small one. The Flash 50 (REI) almost killed me on the PCT -Eastern Sierra because over size ( I got a bad advice from a sale person !). The next question is What is factory's definition of TORSO and HIP measurement and how to measure it - I would do it by myself. Please help.

I am a woman, 5'11" about 170 lbs, 64 yrs old and am looking for a light weight weekend backpacking backpack. The Osprey 48 looks perfect, but what is comparable to it for a women? Could I order a mens small or medium and have it work? Thx

I am a male, about 5'11 165 and I have the large size, while men's and women's sizing differs a little I think going to a medium would probably work. The major thing to note is the hip-straps are not removable so you can't switch for a smaller or larger hip-belt like some other osprey packs.

Thus far I have used this on a few three-day backpacking trips in the Rocky Moutains of Colorado. Overall I find this to be a very good balance between light-weight and comfortable carrying capacity.

I can say that my approach is right between minimalist and comfortable camping, leaning to minimalist. For me the max capacity is about three days worth of gear/food (~32-35 lbs). Though that exceeds Osprey's recommended upper limit, I believe the pack handles that load fine. Great pack for me as I will rarely go on longer than 3 day trips and will use it for its sweet spot overnighter with two long days. I can easily see using this for long day hikes too.

I can't emphasize enough the importance of trying on this pack. It is not highly adjustable and relies on a relatively close match to the wearer's contour to achieve successful weight transfer. Medium fits my broad back, shoulders and waist and long torso.

A couple niceties-
-The type and size of the pockets are nice for me and helpful for organizing.
-The breathable back-panel makes it super comfortable in reducing overheating on the back.
-Appears durable

A couple downsides-
-While the belt is effective, it's not the most confidence inspiring. I would like to see the width of the belt straps a taste wider. (Maybe because I load a bit more.)
-The side mesh pockets are stretchy but just large enough to fit a standard water bottle when the pack is full.

i hiked with this pack on the appalachian trail, it was super lightweight and had pockets just where i needed them. i highly reccommend this pack to people who serious do not carry a lot of gear otherwise you wil struggle to fit everything in.
the pack felt great when it got really hot and never did feel like it as too hot to carry as it ventilated well.
excellent buy. osprey always stand by their gear. great reputation

I bought this backpack and also the bigger version, Exos 58 to compare. They are both good although I feel the bigger load possible in the 58 puts too much strain on the thin harness and hipbelt, also pulls it more back (more pressure on your shoulders).
My only complaint with both - and a big one: the frame squeaks! The stretch material attached to the frame squeaks when it moves - which it does with every step, at least for me. Is it really just me? Some specific posture and way of walking? I am quite surprised that after searching the web I haven't found any single reference to this. And it's really annoying after a while, I can tell you (unles you hike constantly past rushing waters and waterfalls, that is:-))
Anybody having this problem? Possible remedy (waxing the frame, etc.)? I don't want to have to return those otherwise great packs. Jiri, male 6'3'', 34'', both L size packs.

Unfortunately, the packs that are not adjustable will only fit the Large torso, Large shoulder harness, Large hipbelt sized person. As for adjustability, the Aether series will fit your needs--you can get a medium hipbelt and medium shoulder harness for your large torso--but they only go down to a 60L pack. You might consider the Ariel--which goes to a 55L pack--in a L and swapping the women's harness and hipbelt out for men's harness/hipbelt...

i'm 5'11" 165lbs 32" waist, and I have the large. The waist belt is just about as tight as it goes, but it helps if you put stuff in the pockets on the waist belt and it is more comfortable as well as snug.

Initally bought the smaller volume for light overnight canyon hiking in Grand Canyon. Got the size bigger to accomodate extra food and water. On the first trip out, I broke the stow-on-the-go trekking pole strap - since retied and good as new - and also broke one of the plastic compression cord buckles. I also noticed that one of the other buckles was definately stressed. Second trip into the Canyon, and I popped a seam on the inner pocket, the one accessed by zipper. All in all, I think its a good pack for the weight but not super durable. Having used it several times, I really like the ventilated back feature which also provides nice suspension and cushioning, but the pack definately will not withstand any abuse. I'm constantly worried about something failing on account of weight savings subtracting from component strength. I'll let you know if I ultimately keep it or trade for a more durable cousin. stay tuned...

Took this bag down the AT in 2009. 150 days of constant abuse. Great pack. It was comfortable and lite. This pack was also much more durable than I thought it would be. I used the same pack this season in Montana and it is still in hikable condition. Worth the money. In fact I will purchase one for the CDT in 2011.

hi all, just want to let others know that this bag will fit within the dimensions of carry-on size requirements. i know it may not seem like it at first glance, but as long as you do not have the bag stuffed to the seams, the contents should fit within the outline of the bag's wire frame, which is just within carry-on specs.

also, given the bag's material, i have been skeptical of using it as a checked bag - unless placed in a protected bag/duffle, etc.

I can't; but I'm old and not so limber anymore. But for me it's no big deal, I use a 100 oz. reservoir for hydration, and if I take extra water along on a desert trip or something else with limited or no water sources, I put it in a Platy bottle in the side pocket and usually use that water for cooking or if need be, drinking at a rest stop. I primarily use the side pockets for my rain jacket or similar items that I don't need to get to in a hurry. It's a great pack; do it. ;-)

Edit/Update: I read the question as you asking if anyone can get a water bottle in and out by oneself, with the pack on. I can certainly fit a Nalgene in the side pockets, but I can't reach back to get them in and out with the pack on. Hope that helps.

cay3106765

must admit that i cannot recall exact diameters, but you will not be able to fit a typical nalgene into the side pocket - unless the main compartment is mostly empty. for the last extensive trip i did with my pack, i kept a 1 liter platypus (less than full) in one of the pockets. i think playtpus-like bottles will work better than rigid-construction bottles - unless your bottle is of a small diameter.

also, the mesh pockets (with their side access) are fantastic for small things like cameras, maps, etc. i am able to reach around and pull out contents via the side access. very nice...

The small would be too small for any ease of use if you could even get it on a loaded backpack. Especially if you were using the M or L version of this pack you would not be able to use the S raincover. I would definitely go with the M UL Raincover. The difference in weight between the two sizes of cover is minimal too. Osprey says it is a .25 oz difference.

I love this bag for 3-season overnighters, weekenders, and multi-day outings, running a solo tent or bivy sack, down bag, half pad, Jetboil, and going conservatively on food (I don't eat a ton on the trail). I downsized from an Atmos 65 and could not be happier. It fits like a glove, and although I rarely exceed 20 lbs., it feels better than the Atmos did, and that is saying a great deal, as that is a nice pack. I am quite happy with this bag, and haven't had any issues with comfort or durability. I recommend it highly, and especially since it is on sale right now. :-)

hi everyone... i am considering this 46L pack, and i would really prefer to not go up to the 58L version. i have read from several accounts that the 46L packs more than it should. might this be because osprey reports only the main compartment's volume? thanks,

Sam Reese

it is because there is no certified definition of what a liter of displacement is... Is it a liter of something light? or a liter of sand?

Often there are claims that some bags are more generous or less in size estimates. Hope for it, but don't count on it. If you must have a larger pack... well...

James Phelan

Member since 
Responded on

I hope that Mr. Reese is kidding. A liter is a liter no matter if you fill it with lead or feathers. The feathers may pack to 1/2 liter because they are compressible, but that doesn't change what a liter is. To answer your question, I have heard this of the Exos series also and the best argument that I offer is that they do not count all the small pocket volumes in the advertised measurement. For example, the two side mesh pockets and the hip belt pockets are probably not counted in the advertised volume but they are wicked roomy!

My girlfriend is 5' 10" and 130 lbs.. the medium pack suits her great. I'm a skinny (and tall) male and the medium works great for me as well. Just based on anecdotal online info, skinnier hips and people seem to like this pack.

For eg. larger people than me seem to complain (online) that the bottom of metal frame pushes against their back while it doesn't really touch me much.

Thanks, longhiker. I wrote this a while back. I ended up with the slightly heavier women specific pack of similar construction. No kidding about metal on bone! But this being backcountry.com, no problem! If those metal "wings" come anywhere near your body, reconsider! Contour makes the pack a little more difficult to stuff, IMO.

This is an excellent lightweight frame pack for day hikes or lightweight camping. I have taken this pack on a 4 day trip through Glacier as well as a long bike trip. This pack worked perfectly for both trips and I couldn't be happier. Although there is not much to the frame and suspension, it carries weight very well and is very comfortable. This pack remains lightweight while still keeping convenient stash pockets and gear loops which really helps keep gear organized and accessible. My favorite feature of this pack is its breathability. The mesh back and straps allow sweat and moisture to escape quickly without compromising shoulder and waist strap comfort. I would definitely recommend this to anyone and everyone. Definitely my favorite pack for day hikes and lightweight camping.
