Great pack!

Loved this pack, used it very heavily for six months. Rough backpacking in the high alpine desert. Survived all of winter, hiked over 900 miles with this pack on in the six month period, felt comfortable every step of the way, even with loads of 80+ pounds.
Frame snapped, by accident and blame of entirely myself. Wish they had this pack when I returned it, you'll love it.

I'm looking for a pack for multi-day mountaineering trips as well as routine backpacking. How does this compare/contrast to the Aether 85? Will one be better than the other?

I am looking at this pack for hunting. For the most part I will be carrying around 50 - 60 pounds. But with a little luck I will be packing out about 100. I know the pack is only rated for 70 but I was wondering if it could handle the extra weight? no pack is comfy at 100 pounds. Will this one loose its charm? I guess I would ask the same question of the Aether 85.

Responded on

If you're looking to haul that much weight, this would be a good bet. Maybe consider the 110L version, rated to 80lbs.

Responded on

Hey Trev,

I'd definitely stick with the Argon series over the Aether series for that much weight. The Aether would carry the 50-60 no problem, but push it over 70lb and you'll appreciate the added comfort from the Argon's carry.

And since the Argon 110 is built on the same frame as the Argon 85, they'll both handle the same weight fairly comparably. The 110 will maybe organize and carry larger things efficiently, but if you see yourself needing more than 85L of interior volume, go 110L for sure.

Responded on

I have the 110L version and you'll have no problem carrying 100lb.

Like it so far!

Only had this pack for a few weeks. Used it on a 20+ mile backpacking trip in Moab, UT. Worked great. One complaint, however, is the small stretchy pocket on the outside has a pin hole in it from where it snagged on a boulder. The material is not the type of material that would withstand sharp or tear situations. Only other complaint is the pack does not come with a drinking hose magnet for the chest strap like the smaller water bladders do...nor does the pack come with a water bladder and hose. You can purchase these in a package for additional $$, but I would have liked to see them come with the pack for as much money as I paid for it. Overall I am very pleased with the pack so far however. I would recommend it to a friend. I own an Osprey day pack / water bladder (3L) and love it as well.

Don't like it

It's comfortable, but there are enough annoying problems with it that I'm returning it. I won't go through the whole list of annoyances, I'll just give you the main ones. First, the detachable top STRAPS on, not buckles, which is maddening. The back portion buckles, but the front of it must be strapped, so you find yourself fumbling with it in the dark or on the trail or in the airport. Second, the side pockets you should be able to reach into on the trail aren't accessible because either the zippers are impossible to work while you're wearing the pack or the because the pockets are just out of reach. Third, and most maddening of all, no matter how you pack it the damn thing will not stand up. When you take it off and set it on the ground it rolls over onto its back, getting the pack and whatever gear you have stowed there muddy. This alone drove me so crazy I went back to my old Kelty pack.

Looks Good So Far

I've put my Palisades 80 on the shelf and replaced it with the Argon 85. I haven't put it through it's paces yet but after loading 30 pounds in each and doing some laps ... the Argon is the overwhelming winner!! It all comes down to fit and this one fits me the best.
The Argon is wider and therefore the weight rides lower. The unique, back hugging shape of the Argon suspension also keeps the weight tighter. You just don't seem to notice the pounds with this thing. Can't wait to load it up and hit the trail!!

Couldn't ask for a better pack

Thought I'd write a review of this bad boy after owning it for about 3 years. I've backpacked for about 12 years, and this is the best pack I've had so far. I won't get into all the technical bells and whistles because everyone has their own opinion on that stuff. I've used this pack for ski mountaineering and general wilderness backpacking. I have spent entire days with this pack wading up rivers, sneaking around casting to wary trout while nearly forgetting I had 65 lbs. on my back. Moderate to long alpine trips in the Rockies, 2 months in the New Zealand bush, light loads to massive loads, it really does it all while keeping you as comfortable and pain free as you can be while hauling around a bunch of weight on your back. Don't fret over the price either, worth every last penny.

like your review, but love your photo even more. As an angler i can appreciate not putting down the pack and getting a few more casts in. Most impressive is all I can say. Way to go, and happy trails. I have been wanting to upgrade packs and believe the Argon 85 will be it for my 2100 mile Appalachian Trail adventure.

Can I get a medium torso with a large hip belt?

I'm not positive how backcountry.com does it but at a local rei you can change the hip belt to fit your needs.

Posted on

Hello! I'm sorry for my ignorance, but I would like to know if the difference between the sizes M, L XL regards only the capacity of the backpack or anything else. I'm not so big, but I really need to carry as much as I can in this backpack. Thanks!

Responded on

No need to apologize!

The sizing on this pack is in reference to the torso length. Because the torso length increases the length of the pack, it also slightly increases the internal space.

HOWEVER!!! Do not get this pack based on internal space. Please size your torso (http://www.ospreypacks.com/en/web/sizing_and_fitting) and choose the appropriate sized pack. If this pack fits you, it will carry like a dream and you won't notice the weight on your back. If you get a pack that is too big, you won't carry the weight correctly and it will be a nightmare's amount of uncomfortable!!!

Hope this helps!

Argon 85

This pack holds a ton of gear very comfortably, thanks to the belt and suspension, but it is a bit heavy as a trade-off. I can't afford a separate (lighter weight) "climbing" pack so I manage just fine with the extra weight.
BE SURE TO TAKE CARE WITH SIZING AND CUSTOM BELT MOLDING!
I was shocked during my purchase to find that I was barely a size Medium (I wear L - XL everything) so make the effort to be sized and fitted, as well as having the belt custom molded to your body (Authorized Osprey dealers have a trick little oven to do this) the result is a pack that I can carry 50lbs in all damn day without losing my smile.

Comfortable, but it takes practice to load and adjust correctly

This bag can definitely take the weight. With 2 weeks of expedition gear and rations being hauled over boulder and snow fields, around steep ledges/ lakes/ reindeer trails... I always felt like I could count on this pack to not destroy my back/ hips. I really like the side water bottle holder that is a type of nylon fabric and keeps a 1 liter Nalgene completely secured away. I also tucked my map for the day into this pocket with the water bottle. The brain is a good design but I would have preferred one pocket instead of the two (one small one large-- the small is useless). The outside mesh with the osprey logo on it is a waste of material in my opinion, but came in handy for picking up random trash. The gear loops on the bottom of the bag I cut off mid trip and fashioned them into a belt for my pants when I lost mine, I wasn't sad to see them go as it was one less thing that could potentially snag. The brain I would also take off and empty and use as a seat around camp to keep dry and warm. It's supposed to be a day pack but it wasn't ever particularly useful for me-- it wasn't comfortable to wear as a fanny pack and too small to keep a essentials like an extra layer, first aid kit, and water in for a day hike. That being said, I do like the false bottom and compression straps for keeping a small load in a large pack for impromptu peak ascents on an expedition.

The bag material is good quality, this is my second osprey bag and the other I use for canyoneering. Both have taken a serious beating on rocks and still look new.

That being said, this pack is kind of like a fancy car in the outdoor world. It looks good, but it isn't always the most functional for the way that I've taken a liking to packing. Too many straps/outside pockets and with the frame, it can be hard to really stuff the bottom of this pack full. I'm a big believer in keeping everything your hiking with secured inside the pack so you're not leaving a gear trail to your campsite, and to keep everything dry by lining the bag with a garbage bag and tying it off at the top.

Overall, I like this pack and I'll continue to use it, but the next expedition pack I get won't have so many external pockets and other features that are really more of a design element.

Comfortable, but it takes practice to load and adjust correctly

Great pack and great company

I bought the Argon 85 in 2010 but an injury prevented its use until a few weeks ago. When assembling my gear, I noticed the hip belt had not been shipped with the pack. I called Osprey and they immediately shipped me a hip belt, and they covered the shipping cost for a two-day delivery. Unbelievably great customer service!. And as stated by others, the pack performed great...comfortable and well organized.

Hey. I'm a big guy (6'5", 300 lbs, 42"...

Hey. I'm a big guy (6'5", 300 lbs, 42" waist, big, long torso). Any other big guys out there have experience with this? How's the fit? I'm thinking about retiring my "vintage" external frame pack--which I've customized a great deal to make it fit comfortably. I'm looking at a variety of 80-90L internal frame packs.

Any feedback is greatly appreciated!

Best Answer Responded on

Just because you are 6'5" doesn't mean you have XL torso length--you may fit better a Large torso better but still need those XL components. You could get the Argon/Aether 85L but exchange the L hipbelt/harness with Osprey for XL waist belt and shoulder harness to better fit what sounds like a XL build.

To measure your torso, have a friend measure your back along the spine from the top of your hipbones (run a finger from the bottom of your ribs down your sides until you feel the top part of your hipbones) to the knobby bone at the base of your neck (your C7 vertebra). With Argon/Aether, if your torso length is bigger than 22", go XL. If not, go L. (Note that all Argons come in the XL torso length, but the Aether only comes in XL in the 70L pack.)

My best guess is that you'd be an XL, but after years of pack fitting, I am always surprised by the lack of relationship between height and torso length.

ALSO no matter which pack you choose to go with, make sure you get your Argon/Aether hipbelt heat molded at a local shop if you can. Heat molding will ensure the best possible fit for both Aether and Argon series packs.

Responded on

I'm a big guy too (just not quite as big) at 6' 3", 265 lbs (used to weigh 310), 42" waist. I scoffed at the thought of getting a Large instead of an XL but when it came down to it, the L fit *ME* better (I'm fairly proportional too, though tend to be a tad more leg than torso). I was even more surprised to find the L hip and chest straps fit rather than having to go with the XL too.

As an avid cyclist, I'm accustomed to having all my outdoor gear ideally sized for people half my size forcing me into 2 and sometimes 3XL (or 7XL Euro-size!) shorts and jerseys. The Osprey's size was quite a pleasant surprise.

This is all to say that fit is everything. Before dropping the bills online based on preconceived sizing notions, you might want to try some out in person if you can. To be sure, my intent was to do just that- shop local, buy global- to save some cash. But I lucked out and was fortunate enough to find this pack not only in my size locally, but on sale too!

Happy trails,

Takes Load Well

OK. I'll try and make this straight to the point and clear. I wouldn't go as far as to say that this is the best pack ever. It doesn't have every feature I'd like for mountaineering. For example, it could use some webbing loops like two daisy chains or something for more strapping. However, it is definitely a good all around pack and it's definitely a good purchase. It carries load much better than my last pack which was something closer to a rucksac made by REI. I recently took the pack with me to climb Mt. Shasta. I hauled up tons of gear including a 60m climbing rope to practice some snow climbing stuff. The most packed it got was on the descent from base camp. At that point rope, sleeping pad, probe, shovel, ice axe, crampons, snowshoes, helmet, WAG bag, top rain/snow shell, were all strapped on the outside of the pack. The rope, top shell, and WAG bag were secured under the top flap. It was a little awkward getting it all strapped on. I tie a cordlette using four small loop sewn into the front of the pack. Things definitely fit better when I'm wearing at least one of either my crampons or snowshoes so that both aren't strapped on. The shovel head fits well in the front wide pocket. The hip belt comes out, but I'm not sure from which points I would haul the pack from. I personally like the bottom access...I put my sleeping bag and bivy sac in there (easy access). The top flap has lots of space for store oft-used items. There's a strap inside at the top that compresses from the top. I found this useful for securely the rope as well. The fanny pack option is a little annoying. The buckles come out and get in the way. I don't even like the concept of a fanny pack...I prefer bring a super thin stuff sack type pack (but I don't normally do that).

Best Pack EVER

I cant praise this pack enough...
Most amazing most comfortable pack I have ever used
Ive had it loaded with over 120lbs of tools water and food for a week long remote trail work trip and it was like a pillow on my back
well balanced and doesn't cause you to bend over when carrying heavy loads
Would buy again in a heartbeat...you get what you pay for and this is no cheap Kelty...

Replacing my uncomfortable military internal frame. I have used my old pack for my last 2 trips to Yellowstone's backcountry. This year I will be going for ten days nine nights. I want the best on the market, and so far this one is at the top of the list. Which would be better for my trips in Yellowstone, the Argon 85 or the 110? I'm 6', 215lbs.

Responded on

This is a great pack. World of difference from the old Army stuff. The other one would be the Arcteryx Bora 80, or if longer trips and bigger loads are the norm, the Osprey Argon 110 would be the way to go, or the Arcteryx Bora 95. Both of latter packs are "HUGE". Between the Argon 110 and the Bora 80 I own, I prefer the ride and fit on the Arcteryx. For that kind of trip length and load, you really should inventory the gear you plan on hauling, and also see if there's any way to try them on first, even if it means ordering both/all at the same time and returning the one(s) you eliminate from the running. You can even take them out and field test them, and BC will still let you make the return for a full refund (less shipping).

Responded on

Phil is right, these are great. To answer your volume question, about the 85 or 110, you should consider the type of gear you generally carry. Personally, I'd recommend the smaller pack.

Ask yourself these questions
Will you be carrying a lightweight, high fill power, down sleeping bag or a cheap bulky 0º synthetic? Does your shelter weigh more or less than 2lb/person? Does your kitchen consist of a single titanium pot, or are you bringing your stainless pot set and nonstick pan? Are you bringing more than one set of clothes? How bulky is your sleeping pad- A 14oz Neo Air or 2lb Trail Light? Do you plan on bringing heavy luxuries like a Camp chair, DSLR, Coffee, Fresh fruit/veggies?

A couple of things to consider: The 85L will have a better balance and carry better, because it will weigh less, have a slimmer profile, and by necessity have less crap in it. The 110, a gigantic pack by any trip standard, may ruin you: if you have extra capacity, you'll be tempted to bring extra crap.

The advantage of the 110 is that if you have heavy gear, it will not require you to buy lighter stuff to make it all fit. Also, you won't need to strap anything to the outside of the pack, which not only ruins balance and mobility, but makes you look like a junkshow on the trail. Finally, if you compress the larger pack right, it may fit just as well as the 85L.

I'd personally recommend an 85L as the size for a backpacking trip of any length. I'd reserve 100+ for winter camping and mountaineering.

Responded on

Thanks for the quick and helpful responses. For the record, I will be using canibalized MRE's for the anti-bear advantage(air-tight, burnable trash). I will find out if any of the local retailers carry Osprey for a tryout. I think I'll also measure the pack I've used on my previous trips which was sufficient for slightly shorter treks.

Responded on

Hey there - Simon is right on abaove. Think about your gear. Depends on how much you want to carry. They will feel similar, except, you will have more weight in the 110 (because its bigger!) so it won't be as comfy as it would be if you had less weight! Argon 85-110 are the right choices.
