Osprey Atmos vs Aether


One of the most well-known bag companies on the market, Osprey, is perhaps most known for the comfort of its designs. Therefore, deciding between the Aether and the Atmos, Osprey’s two most well-liked backpacks, can be challenging. In addition, both Osprey Atmos and Osprey Aether provide product variations with various capacities. 

Long trips or long hikes are appropriate uses for both backpacks. Therefore, the Osprey models, the Atmos, and the Aether belong under “big backpacks,” designed for overnight or extended travel. You may decide between the two by considering the various characteristics each offers and your needs.

Osprey Atmos

Atmos models are widely sought-after backpacks for weekend getaways or multi-day journeys where comfort and breathability are essential. In addition, due to its various features that make carrying a lot of gear easier, Osprey Atmos is the backpack of choice for many hikers and backpackers.

It covers your back and hips in 3D suspension mesh as part of its AntiGravity suspension, which prevents you from feeling the weight of a fully loaded backpack. Additionally, it keeps your body away from the backpack, lowers sweat, and makes carrying simple thanks to the back mesh that stretches along the back to the hip region.

It has a removable top lid, and a flap cover that assures your valuables will remain dry matter the weather. In addition, the top lid can be entirely removed without compromising the security of the contents held inside. 

It offers dual-access stretch mesh side pockets for storing water bottles and other supplies. An inside reservoir sleeve also increases your options for hydration. On wet days, the backpack’s inbuilt rain cover is an absolute convenience.

All Osprey model Atmos and Aura bags have a fixed suspension and are available in different sizes (S-M/L-XL). Between these sizes, there are around 3-kilogram weight discrepancies. Depending on the style and if you choose a small, medium, or big size, it usually runs from 47 to 68 liters. 

Osprey Atmos AG 65, Atmos AG 50 for men, and Aura AG 65, Aura AG 50 for women, are available from Osprey. You can select the model and size according to your requirements.

Osprey Atmos Features

Osprey Atmos offers a fresh take on fit and comfort in big bags while being incredibly useful. If we list the features of Osprey Atmos models as follows:

  • The main compartment’s top loading design and padded 3D suspension contour enable upper body mobility and breathability.
  • Compression straps on its top and bottom sides minimize bulk and support the load for ideal weight distribution and comfortable carrying.
  • The top load lifters and pack’s central core are connected to the hip belt by the LightWireTM peripheral frame to distribute the load.
  • A great fit is provided by the Anti-Gravity ventilated mesh back panel, which automatically adjusts to the body to distribute weight.
  • The Fit-on-the-FlyTM hip belt and adjustable strap let you customize the fit for the best possible comfort.
  • Two zippered compartments with mesh attachment points, a removable floating top flap, and a key clip are all included in the bag.
  • When used without a cover, the integrated FlapJacketTM shields the contents from bad weather and rain.
  • Snacks and other small items are kept near the hip belt pockets with zippers.
  • Stretch mesh side pockets with dual access make it easy to carry small items like a lip balm or compass.
  • InsideOutTM compression straps with dual top and bottom sides moderate loads and create an aerodynamic profile.
  • A front stretch mesh pocket, two ice tool loops, and a Stow-on-the-GoTM trekking pole attachment are additional exterior features of the backpack. Consequently, you always have access to free hands.
  • A sleeping bag compartment with a detachable zipper is located at the bottom of the bag.
  • Internal hydration sleeve included; separate purchase required for a hydration reservoir.
  • An optional removable zipped sleeping bag compartment is located at the bag’s bottom.
  • A safety whistle is built into the sternum strap and removable sleeping pad straps.
  • The bag has an inbuilt rain cover to protect your goods and bag in inclement weather.

Osprey Aether

Osprey Aether is a backpack with different sizes and designs with varying carrying capacities. The Osprey Aether AG 60, Osprey Aether AG 55, and Aether AG 70 models, as well as their small, medium, and large sizes, are all part of the Osprey Aether AG series. 

There are additional Osprey Aether models out there. The Aether can support a substantial weight thanks to its capacity, which varies according to the design but typically falls between 57 and 88 liters.

Although the AntiGravity 3D suspension technology is also included with the Osprey Aether AG models, the Osprey Atmos is more breathable. Additionally, this backpack contains a ton of compartments and sections for structured storage and secret pockets, all of which are pretty useful. 

It is much simpler to find what you’re looking for without digging through everything because its main compartment is accessible from both the top and the side.

The adjustable hip belt, which makes this backpack fit much more comfortably and distribute weight better, is another of its best features. In addition, it has a chest strap with an emergency whistle attached, just like the Atmos, in case you need rescue while hiking.

Like the Osprey Atmos, its top cover is removable. The top flap of the backpack, in the version offered in the US, can be folded down to become a backpack, making the Osprey Aether not only capable of carrying a sizable amount of weight but also allowing you the freedom to travel with a considerably lighter bag. The EU version of this bag is not, however, obtainable. An integrated rain cover is used in its place, which is very practical.

Osprey Aether Features

The Osprey model, the Aether, is a customized, ideally fitting pack with the capacity to carry bigger and heavier loads, making it perfect for a week on the trail or an entire weekend. If we list the features of Osprey Aether models as follows:

  • A thin suspended mesh panel that runs the length of the backpack’s upper body and down to the waist is present. This offers breathing comfort as it hugs your back.
  • The thermo-moldable hip belt and harness provide fit and comfort for individuals carrying large loads and traveling long miles and are replaceable for a custom fit.
  • The bag’s top flap can be taken off and used as a practical backpack or left at home to save weight.
  • Loading and unloading are made simple by the front panel of the bag’s extensive J-zipper main compartment access.
  • The bag has two front compression straps, and two top-side, and bottom inside-out compression straps.
  • Storage and convenience are provided by zippered hip belt pockets, a large stretch mesh pocket on the front panel, and side stretch mesh pockets with dual access.
  • The bag has two ice tool loops with bungee tie-downs and a Stow-on-the-Go trekking pole connection. Thus, you always have access to free hands.
  • The backpack has side water bottle pockets with dual access made of stretch mesh.
  • Straps for a sleeping pad are removable from the bag.
  • The bag has a removable divider in its zippered sleeping bag section.
  • Internal hydration sleeve included; separate purchase required for a hydration reservoir.
  • The bag has an inbuilt rain cover to protect your goods and bag in inclement weather.

Osprey Atmos vs Aether

The Osprey Aether and Osprey Atmos are both well-made, functional packs. Though none is better than the other, you should think about how their features match your requirements. Let’s compare some features to help you understand which of the two backpacks is right for you.


Hikers frequently cite fit as the most crucial hardness requirement because a small mismatch will make you feel considerably worse.

However, the Atmos is often better suited for comparatively lighter weights because of its increased adjustability, improved rear panel suspension, and more lightweight construction. In contrast, Aether’s strong hip belt, more robust overall suspension, and convertible top lid daypack make it more practical for relatively heavy loads.

The Osprey model, the Atmos, also includes a movable hip belt that can be adjusted to fit persons with larger hips (there are small extenders you can pull out up to 6 inches). In addition, the mesh’s placement on your shoulders and the length are entirely customizable.

The Osprey model, the Aether, has combined its popular, old-school adjustable torso system with some of Atmos’s anti-gravity mesh characteristics. The lower parts of the back and the hip region are covered in mesh. More padding, mesh, and airflow holes are on the top. In the Osprey model, the Atmos is more “breathable,” thus this is less so.

The Aether’s replaceable harness allows you to customize the length and fit, another essential feature to keep in mind. The hip belt is also highly traditional, yet it still features heat-moldable foam that can be shaped to fit your hips precisely. To purchase this, you must visit a licensed Osprey dealer.

Capacity and Comfort

Starting with capacity, a critical factor in separating these two designs, the Aether backpack is made for longer excursions, which accounts for its bigger capacity. 

A more durable structure is necessary for a bigger carrying capacity, typically increasing the product’s weight. The heavier substance is consequently Aether when compared to Atmos.

In terms of comfort, the Osprey model, the Atmos, is the better option for a backpack. This is because of its AntiGravity suspension system, which is made exactly and provides a lot of airflows. However, the Aether’s adjustable hip belt is also a highly comfortable element in terms of fit.

Durability and Warranty

Both designs are highly sturdy, and it is difficult to tell which one will hold up to use better. They are both constructed from Nylon Dobby fabric, which has a range of thickness and weave.

Osprey comes through on the guarantee front and provides a Lifetime Warranty for both designs, including free repairs for minor damage or a replacement should this damage be irreparable.

Compartment Access

Like any trekking bag worth its salt, both feature full access. In addition, both also feature bottom access and separation panels that can create a separate bottom section for other gear.

The Osprey model, the Aether, features a long vertical side access zipper, which is a great addition and gives you another option to access your goods. You can now access mid-level areas without digging for your items. Then, of course, there is yet another item that makes the pack heavier.


The Osprey model, the Aether design has extra features that make it significantly more adaptable, whether you are looking at the US or EU versions of the bags. First off, its enormous size and hidden compartments make it considerably better suited for transporting heavier things. Those who prefer light travel will find the convertible top flap a handy bag.

The main drawback is that this function makes the bag heavier, so Atmos might be a better choice if you don’t need it. However, for individuals who prefer shorter travels, the Atmos is a much better design because of its smaller size and cozy mesh panel.

Which One Is Better?

Osprey’s backpacks have a lot in common, yet they serve different purposes.

Due to its lesser capacity, the Osprey Atmos is more appropriate for journeys under five days. It is constructed to last, quite functional, and extremely comfy. One of its best qualities is that it is ventilated, which makes it an excellent backpack for warmer weather.

On the other hand, individuals doing longer travels should think about the Osprey Aether because of its many pockets, larger size, and design meant to carry heavy things. 

Given that it does not allow for much ventilation, this backpack is also excellent for chilly climates. In addition, it is highly adaptable and comes with either a convertible top lid (US) or a rain cover (EU).
