Product Description

Product Description

Overnight to week-long trips, features floating top pocket, 2 side zippered front pockets, zippered sleeping bag compartment with removable divider, 2 ice tool loops with bungee tie-offs, and removable sleeping pad straps

When first introduced, the Atmos Series of hiking packs turned heads and attracted devotees instantly, and the 2009 version is no exception. The Atmos 65 is equipped with Osprey's AirSpeed suspension system, which combines a LightWire alloy frame with a 3D tensioned mesh back panel and side crescent ventilation. This ventilated design is built for comfort, with all contact surfaces made of either breathable mesh or perforated, molded waffle foam. As a result, the pack fits your body perfectly, with no hot spots to distract you whether you're bagging a fourteener, hiking the Appalachian Trail, or pulling your next 24-hour race. Further comfort stems from the BioStretch mesh-covered foam harness and hip belt, which team up to distribute the weight evenly while providing a comfortable fit. And, of course, the top-loading Atmos 65 offers several storage pouches for your gear, including a large main compartment, a removable floating top pocket with an under-lid mesh pocket, two vertical zippered front pockets for easy-access items, and an adjustable stretch-woven front pocket.

The pack also includes a sewn-in hydration sleeve with a well-marked exit port, ensuring that you stay well hydrated on the trail. And serious trekkers will love the Stow-on-the-Go trekking pole attachment, which leaves both your hands free for climbing. Other details include a zippered sleeping bag compartment with a removable divider, dual ice tool loops and bungee tool tie-offs, and a couple of dual mesh side pockets with InsideOut compression, which allow you to tension and secure your load easily when the pockets are in use. The pack--which is available in graphite grey, green apple, and aspen gold colors--comes in small, medium, and large sizes.

The Atmos 65 includes a pair of vertical zippered front pockets and a trekking pole attachment.

Backpack Guide
Finding the Right Backpack
For extended trips into the backcountry, there's no getting around the fact that you'll have to carry life-sustaining supplies on your back. Here are some things to keep in mind when shopping for a backpack:

Internal vs. External
Up until late 1970's, external frame packs--which consist of an exposed, lightweight metal frame attached to a fabric pack-bag--were the only thing going. In recent years, though, packs that place the support structure of the pack inside the pack, known as internal frame packs, have boomed in popularity.

The good news about internal frame packs is that they hold the weight of your load close to your body, making it easier to maintain your balance on uneven terrain. Meanwhile, internals provide stiffness and support, but they are not completely rigid, which makes them more flexible when you're doing active sports. With the added flexibility comes a high degree of compressibility, meaning you can use the pack's compression straps to cinch down your load and keep items from shifting and throwing you off balance. Internals also sport slimmer shapes that allow for more arm movement in all directions--another big plus for off-trail bushwhackers, skiers and climbers. Last but not least, internal frame packs offer a greater range of adjustability in the shoulder harness and hip-belt than external frame packs.

There are some negatives for internals. First, once packed, it can be difficult to grab needed items out of them quickly. And because internal frame packs consolidate the load into a single, body-hugging unit, proper packing is very important. To distribute the weight properly, you should pack your heaviest items close to your back and in the middle portion of the pack-bag. Plan on getting a sweaty back with an internal, too, given the fact that they are pressed right against you. Finally, internal frame packs are priced higher than external models.

External frame packs are very good at focusing the weight of a load directly to the right place: your load-loving hips. While internals, when properly packed, do this effectively, too, you can always rest assured that an external will distribute the load evenly, no matter how unevenly packed it may be. Externals also offer easy access to your gear via multiple, easily-accessible compartments. Plus, because externals don't situate the load directly against your back, you'll enjoy far more air flow. Finally, if you're on a budget, or you're buying for a growing child, externals are more affordable.

If you plan on hiking on easy to moderate trails and you don't need a lot of body movement, you'll probably be fine with an external. But because externals are so rigid and inflexible, challenging trails or any kind of off-trail pursuit can become painful and frustrating. Also know that your balance is far more compromised with an external frame pack during activities like stream crossings and hops through talus fields.

Packs for Shorter Trips
In addition to backpacks designed for overnight trips, rucksacks are great for day-trips, warm-weather one-nighters, single-day ski trips, or fast alpine assaults. Some rucksacks blur the line between backpack and rucksack with integrated internal supports and sophisticated hip belts and shoulder harnesses. Choose a pack in this category based on your intended use. Short day hikers don't need an internal frame, while climbers and skiers with heavier loads likely do.

Sizes and Capacities
Packs in the 3,000 cubic inches and lower category are good for day hikes or overnighters in warm weather with minimal gear. Packs in the 3,000 to 4,000 cubic inch range are good for one- or two-night trips in colder weather. If you're going to be out for up to three days, look for a pack in the sub-4,000 cubic inch range. Choose a pack with 5,000-6,000 cubic inches for week-long outings. And finally, for trips lasting a week or more, you'll need something in the 6,000-plus cubic inch category. Keep in mind, though, that bigger packs weigh more, and since every ounce counts, you'll want to choose a pack that offers just enough space for your outings and no more.

I have a slightly earlier model of the Atmos 65 that's two years old and differs slightly from the new model. In mine the internal frame is shaped to curve well away from mesh against the wearer's back. This allows plenty of air circulation (and I use this space to hang my hydration bladder), but it reduces the size of the pack's main compartment, so much so that some large items, particularly bear canisters, may not fit. The new one reduces the curve to keep the compartment a bit closer to the wearer's back, creating a larger cargo area, while still leaving plenty of room for air to circulate. That's one of the distinctive features of this pack; the ventilation area between the mesh against your back and the cargo compartment keeps your back cool and dry. Also, the frame material in the new model seems to be a bit lighter, and it has a feature to allow carrying trekking poles by your side so you can stow and retrieve them without removing your pack.

But everything else seems to be the same. I like the pack for it's lightness (it's the lightest frame pack of this size I could find) and its design. The hip belt and shoulder straps are very comfortable and they keep the load close to your body, so it rides very well. It has several nice details and compartments that allow plenty of options for load distribution but it isn't overrun with bells and whistles, such as extra straps and buckles that don't seem to be needed, as I've seen on several packs. It's hardly minimalist, but it has what you need and not much more. I've had several packs over the years, both internal and external framed, all from well-known brands (Kelty, Lowe, etc.) but this one is the best I've had by far. My most recent use was on a 12 day trip through the Adirondacks and the Osprey came through with flying colors.

The Osprey Atmos 65 is an unbelievably well-built pack. It is light, the pockets are in just the right places and it carries the load well. I bought it to replace a very worn Kelty which I had used for years as my "heavy" daypack (I have a couple of activities that involve 30 lbs of day gear, this pack is really an overnight/weekend pack). I immediately tested it on a 4,000' elevation gain snow hike and was amazed at how well the air-back works to keep my back cool and dry. At first it's a bit unnerving to not have your back sweating like mad but remove the pack in sub-zero after two hours of going up hill and things are great. Very little sweat, very little "chill".

I next took it for a couple of nights backpacking. It fits 30-40 lbs of gear very well. Once again, the thing I noticed was how well the pockets are designed and the attention to detail. The compression straps work great, it is easy to attach trekking poles or ice axes, and those attachments work for other things like drying socks. The back "shovel" pocket works for a snow shovel but also is just the right size for wet tarps, ground clothes, and bear lines.

My Aether 75 sold me on Osprey a few years ago but with the Atmos 65 I am a TRUE BELIEVER!

Size: LargeColor: Graphite Gray Verified Purchase
First My Overall Impressions:

Pack rides comfortably
Your back can breathe
Plenty of storage for a few days of roughing it
Plenty of pockets
Lots of little features that add up in a big way

The belt pockets are just little to small (barely).
The buckles, all of them, feel insubstantial

Detailed Review (Kind of):

I'm not going to be able to give testimonials to match those with hundreds of miles per year, but even for my limited hiking use, this pack was amazing. I did a an 16 mile weekend hiking/camping trip; 8 miles out, camp, and 8 miles back. I was looking to test the pack, and get some exercise so I loaded down the pack with 50lbs of redundant gear, water, and some things I actually needed.

To the pack's credit my legs were the only part of me that was soar at the end of the first day. The pack's support feels secure. It does not shift and the mesh backing maintains contact with all of your back the entire time, even when leaping about.

There is not a lot of vertical adjustment that can be done with the pack, so make sure you're in the size range before purchasing the pack. The adjustment options that are available were sufficient for me, nothing spectacular, but nothing awful.

The mesh touching your back breathes. I sweat a lot (pleasant I know), but I finished this hike with an almost dry back. I loved it. Even the belt and shoulder straps are a mesh fabric with foam padding that has holes for letting your body breath where there is contact.

The main pouch of the pack has access from the top (I know that is obvious) and a large access panel at the bottom to access a sleeping system compartment.

Size: MediumColor: Green Apple Verified Purchase
I have taken this pack for a short 2-3 mile hike on a trail that was pretty thick to non-existent in some spots. I love how it's a lower profile pack, you don't really notice it until you are in the situation but when you need to go under limbs and brush, having a larger pack will catch as you instinctively duck your head. The straps are second to none and I love the breathable back. I have yet to try out a lot of the other amenities on it but one I really do like is the waist band pockets! they are great!

Sizing was a bit of a concern for me, here is what happened.

I watched tons of videos and reviews (i might add one myself to aid people in this big decision if looking for "the right pack") I saw one where one guy mentioned that he was wearing a medium-sized pack. I was going to order a large. I am 5'11" size 33-ish waist. I figured ok, that guy looks my size, maybe I'll order a medium. So I ordered the medium and was kinda losing sleep about it, so a few days later I found out that Eastern Mountain Sports is an Osprey dealer, and can fit you for the right sized pack. Apparently this pack (the atmos 65) is kind-of a nitch pack when it comes to measurements, this is because of the fixed-sized belt that can NOT be swapped for a larger or smaller one. The store's trained "Pack Guru" measured me up with this logo-branded osprey pack-measuring device and said that I was a "large torso and medium waist" meaning I need to have a large-sized pack and medium-sized waist to have a correct fit. I was kind-of upset that I ordered the medium but the guru told me that "it's not an exact science, bring the pack in, we'll put some sandbags in it which changes the way it sits on your hips and shoulders, and we'll double check to make sure it fits you properly.
