Whenever I leave my house for a backpacking trip, my Osprey is always with me. Whether it be the lightweight design, comfortable weight distribution, or the ample pockets, I frequently find myself gawking over the Osprey Atmos 65 L.

Pros:
Fairly Lightweight
Awesome weight distribution
Comfortable fit
Top of the line construction material
Conscious placement of pockets and zippers
Aesthetically pleasing
Dries quick

Cons:
A little on the heavy side for thru hiking
Too many pockets (if you hate pockets)

All in all, the Osprey Atmos 65L is a great gear choice for beginnning backpackers and seasoned veterans alike.

I have shopped around for several bags and tried hundreds on and this bag is the most comfortable by far! I love the technology for the back cause when I hike I get sweaty and this bag allows me to stay dry.

Instantly fell in love with this pack when I tried it on. The AG suspension system is top notch. Able to fit all my gear and them some without feeling like your carrying around bricks. If your looking for a pack that can do it all then look no further. Do your self a favor and try it out. You will have no regrets.

What a great pack. It distributes the weight of whatever you decide to pack so well that you forget you have it on. A ton of room for whatever you may need while out in the wilderness. I was able to fit ALL of my hiking/camping gear inside without an issue. Even with it filled to the max, it feels feather light.

Would definitely recommend for anyone looking for a pack that can do it all.

This is the best pack you can buy whether you are just getting into backpacking or if you are looking to replace an older pack.

I was very, very reluctant to stop using my passed down Dana Design. I felt almost like a traitor for going away from the legendary brand... But all of those feelings disappeared five minutes into using this pack for the first time. All of what is said about making 45 lbs feel like 30 is true. I did not develop any hotspots on my back, sweat spots or overall discomfort after hours of use. I couldn't be happier with a single piece of gear.

The gear organization is top-notch. Trekking poles, ice axe, foam sleeping pad stored externally all stay tight and organized. The two outside storage zip-compartments fit emergency storm protection and mid layers with easy so you don't have fuss with the main storage compartment.

I recommended this pack to a friend who was just starting to get into backpacking and he feels the same exact way about the pack. Be smart, get this pack, it will be the biggest favor you can do yourself.

I love the AG system by Osprey. It makes a fully loaded pack seem half the weight.

I overloaded this pack for a 2.5 mile hike into camp to test it out on the Superior Trail. 22 degrees, fresh snow at 51 lbs. I felt like I was carrying about 25-30.

I try to make a weekend trip camping once a month in our beautiful state parks here in MN and this bag is my go to. Its so comfortable.

Storage is accessible. Straps are durable. The Cinnabar colour is awesome.

My wife tried the female version (Aura) and wants one asap.

This is the first Osprey pack I have ever owned. Have done countless backpacking trips with this bag and have zero complaints. The AG system is absolutely incredible. Every time I put the pack on no matter how loaded up it is I feel like i'm putting a tight hugging Koala on my back. Osprey really does a great job at providing you with pockets and straps for everything you need and nothing you don't. I'm now a Osprey addict.

This, like the title says, is a early review. I have only taken this pack out for a one night trip, covering 23 miles over the course of two days. But what I have done an extreme amount of is packing, unpacking and rearranging all of my gear in the pack So I guess you can say this review is more of a non physical review, but it still will help in questioning your purchase of this pack. Number one, I have a rather larger down bag I take because I have large shoulders, as well as the longer length in the bag because I am rather tall. Inside the stuff sack that Big Agnes sent with the bag, it fit absolutely perfectly in the bottom sleeping bag compartment (as well as gave the bottom of the pack a nice shape). Every single zipper is quality on the pack, of course you need to be careful when closing a tight pocket, but I have had no issues with being worried if the zipper can handle it. I stuffed by jetfoil mini mo, big agnes fly creek ul2 tent, patagonia down jacket, pants, shirts, socks, underwear, camera gear, 5 liters of water in plastic bottles, as well as some random bits of food for the night all in the main compartment and with how I packed and compressed everything down I still only used about half of the compartment. I then added some head lamps to the exterior pockets, toiletry items, camera tripod, . and a phone charger and the pack just consumed everything. The hip belt pockets are not as small as I originally thought they were going to be because of reading reviews, but I can fit my wallet, phone, as well as a GoPro all in ONE POCKET. The support system if gold on this pack, I threw 50 pounds of weight in the pack just for the heck of it, put the pack on and I can honestly say the pack did not feel a pound over 20. Of course, you need to set the straps up properly for your body shape, but once you dial the setup in, you will be skipping down the trail. Buy the pack, you will be stoked on stoked on stoked.

For this review, I want to highlight the importance of a quality backpack. Obviously it depends on the weight you’re carrying, the length of the trip, and the weather, but let’s say you are at least doing a 3 night trip in the middle of summer and about 25 miles round trip. For this length of a trip it would be very important to be comfortable, ie. having a well-rounded backpack.



My backpack of choice, hands down, would be the Osprey Atmos 65. It has a good medium to high volume capacity and most importantly, it is comfortable. The Atmos, as well as a few other Osprey packs, has a vented, mesh back panel which greatly reduces heat and sweat from your back. This is a huge benefit I’ve noticed especially on those hot days. You don’t have a sponge on your back absorbing all of the sweat. You will still sweat because you are working hard, but you will be much more comfortable. The hip belts on this pack are on the medium size, and wrap around my hips nicely with no pressure points. The top loading compartment is big and has a nice draw string. There are multiple external pockets to throw quick access essentials into. The bottom compartment is perfect for a sleeping bag as well as anything else you have that is on the softer side. The top lid has two pockets that are nice for the “don’t lose” essentials. It also is detachable if you need to use it for a small day hike in the middle of your trip. It contains a hydration sleeve as well, however I never choose to use those. I find they’re too hard to clean and just aren’t that beneficial to ever bring. The overall weight 4 lbs 6 oz of the pack itself is on the medium side. It definitely is not on the ultralight scale. It can take a decent beating. You don’t have to worry about setting it down in rocks and it ripping or falling apart. For its weight though, it brings the best specs and comfort-ability you can find.



I’ve brought this pack up Mt. Rainier, Mt. Baker, Black Peak, and through many other good hikes and I’ve never had and second thoughts. It has all the necessary attachments for ice axes and trekking poles as well as all the compartments one would need. I’ve brought it on 4 night hikes and have had ample room for non-essential things like chairs and beers. I am one to say “go big or go home” so yes there are cheaper options out there, but this pack you would never need to upgrade on (except if you need more space obviously). Yes, there are lighter options out there too, but if you’re carrying over 16-18 lbs of gear, I would definitely choose comfort in your pack over the 1-2 lbs you would lose if you chose a lighter pack.



This is the best pack ever!



size purchased: Medium

I'm 165, 5'10"



Let me know if you have any questions!

This pack is amazing! The anti-gravity suspension puts the weight of my pack all to my hips, right where it should be. And, I don't have nearly as much back sweat! The lady-friend appreciates that. I also love the side access zippers, so that I can quickly access my rain jacket if the clouds start rolling in.



I've found this to be one tough pack. After about 50 miles, my atmos still looks brand new.



I measure at a 19

The Osprey Atmos 65 is comfortable from the time you try it on for the first time to putting it down after multiple days of backpacking. I've carried between 30-60lbs and it has held up under all conditions. I've used it in Yosemite, Zion, and the Tetons among many others.



I would highly recommend this pack for any multiple night trips.



I'm 5'9" 210lbs and use the Medium size pack. I am just at the max for the Medium so if you are slightly taller I'd get the Large.

Nice pack comfortable to carry

I bought this pack as a gift to my friend and backpacking partner, and this is what he had to say:

This backpack is like God's gift to man. The feel of it upon my back is nothing short of pure ecstasy. The antigravity mesh and suspension system is a work of pure ingenuity and genius, and the utility it offers is incredible. If I were forced to pick between this pack and the gift of everlasting life, I would pick this pack. 10/10

Fits amazingly on my body. I have had back issues for a while now so I was nervous to be buying a pack at all... but I picked this up after loading a friends with 35+ pounds and hiking all day. I could barely tell I had a pack on at all! It has many features that allow you to perfectly dial your setup. It could easily hold 55+ pounds worth of stuff or even a week or so long trip. Not to forget that it is one of the more visually pleasing Osprey packs. Above all would be Osprey's ALL MIGHTY GUARANTEE, which includes a lifetime warranty!!! I'm 5'7 and got a medium but you should get fitted because everyone has a different torso size.

I used this on a few hundred miles of the PCT this summer, it was sturdy, reliable, and best of all comfortable: the waist straps are supportive, and there's plenty of adjustment options for the shoulders and sternum, to fine-tune it to your specific shape.

Everything fit fine, and it was no hassle to reorganize as I pulled my gear out in camp.

With the pockets closed I never had problems with critters, although they ate the bite valve of my Platypus system.

I have been using a 59 liter Alps Shasta pack for the last couple years. It was a great starter pack but I was looking to upgrade to something a little bit larger and with a few more pockets. In doing my research it came down to the Gregory Baltoro 65 and the Osprey Atmos 65.

I'm not one for the long backpacking trips; 2-4 day trips are my sweet spot. That being said, aside from the annual 4th of July trip where too much beer is packed, my pack is typically under 40 lbs. In my research, I found the Baltoro to be a very robust pack, a bit heavier, but better for 40+ lbs. I decided the Osprey was the appropriate pack for me, and I was definitely not wrong.

The inaugural trip for my new Atmos 65 was a four day 40 mile trip through the Sierras, with a quick stop atop Mt. Whitney. The pack is incredibly comfortable, especially for the longer 10-15 mile days (although 10-15 mile days are inherently quite uncomfortable).

A quick note to those less experienced packers - if you leave your pack at a trail or around camp unattended, make sure to leave all the pockets open, or hang the pack out of reach of wildlife. A mischievous well-fed Marmot chewed a hole in one of the belt pockets of my brand new pack to get at some crumbs. Not a great start to the use of my brand new pack, but in the end it's supposed to be a rugged piece of equipment so I suppose I can't complain too much.

The pack does a great job distributing the weight. I also like the size of the waist belt. With my former pack, I could tighten the waist as tight as it would go and it was still a bit loose, leaving too much weight on my shoulders. I am also a big fan of all the pockets available and their location; it makes accessing and organizing things very easy, and satisfies my OCD organization habits.

The one complaint I have is regarding the top lid. My previous Alps pack had a lid that could be removed from the pack and converted into a small should or fanny pack. This is a great feature for those backpacking trips where I pack in and stay in the same location for a couple days; I take day hikes and can carry water/snacks for the couple hours we are out without the added weight of a separate pack. After realizing that the Atmos 65 does not include this feature, I inquired with Osprey. Apparently enough people complained about additional weight of the straps required for this conversion, so Osprey removed them. However, there are many ways to easily engineer a strap system and convert it to a pack yourself, so it'™s not too big of an issue.

Overall the Osprey Atmos 65 is a great pack, and I highly recommend it for both beginner and experienced backpackers, looking for a 2-4 day trip pack!

I've been backpacking for years with great packs and never knew I could be as comfortable as I was the first time I used this pack. The first outing was a week long trip and I was ready for the usual soreness over the first few days but it never came. It was also a great upgrade from my older pack with only 3 areas. All the additional pockets really helped organize without adding weight and bulk.

This pack is by far the most comfortable pack out there. The technology in this pack is above the competition. If you are looking for a super solid pack that is going to be very comfortable then I would look no further.

Have like four different Osprey packs they are all great. This is no exception
