What Is Osprey Atmos & Aura AG LT Backpacks Series?

Last Modified: 04/18/2025

In case you missed it, there is something new on the hiking backpacks market, Osprey has launched a new version of its best known series. So what this is about?

Osprey Atmos and Aura AG LT backpacks are two completely new series that Osprey launched for the last season. It appears that the letters LT in the name imply that this is about reduced weight, they describe them as lightweight packs.

Many of the essential features of the standard Atmos & Aura AG packs are still present, but some important features are missing and they are listed here.

About the letters AG and LT in the name

So these are again true anti-gravity (AG) packs, and this is behind the letters AG. You again have a continuous mesh that makes the back panel, and it continues to the ventilated hip belt.

But these are now a bit lighter packs, and to see this it is best to compare. So here are a few numbers:

  • Osprey Atmos AG 50 pack: the volume is 50 liters, and the weight is 4.32 lb (1.96 kg).
  • Osprey Atmos AG 50 LT pack: the volume is 50 liters, but the weight is 4 lb (1.81 kg).

For the Atmos AG 65 the weight is 4.613 lb (2.09 kg), and the LT version weighs 4.068 lb (1.84 kg).

So this is 150 grams difference for the smaller pack, and 250 grams for the bigger. Frankly speaking, the difference is ridiculous when you realize how they have reduced the weight.

Some missing features in the Osprey Atmos & Aura AG LT backpacks

The list below summarizes only the most important missing features and differences with respect to the standard Osprey Atmos and Aura AG packs, and they are given in no particular order. There may be more so let me know if you notice.

1. The suspension system in this LT group is considerably different. The torso length is still adjustable, but here you have a ladder type system with several specific positions for the harness. This is very different from the standard packs. See what the AG LT packs have:

A different torso adjustability system.
A different torso adjustability system.

This is the same system they introduced in their several other series like in Osprey Eja 48 Pack for Women.

2. There is no padding adjustability on the shoulder harness. This feature is available in the standard Atmos & Aura AG packs where you have Velcro connection, so the padding can be moved up or down the way it fits you best.

3. There is no Stow-on-the-Go attachment system for the trekking poles.

4.  There is only one side access with an inverted-J shaped zipper. In the standard Atmos & Aura AG packs you have such access on both sides.

5. There is no bottom zippered sleeping bag compartment.

6. The lid is with only one zippered pocket. You have them two in the standard Atmos & Aura AG packs.

7. The two larger packs in the Osprey Atmos and Aura AG LT backpacks do not have two zippered front pockets. They are available in the two largest standard Atmos & Aura AG packs.

My experience with Osprey Atmos AG LT packs

Actually, I have one of them, and it is presented in detail in my Osprey Atmos AG LT 65 pack review. The pack comes with a ventilated back panel and this is its best part. 

But I do have an issue with its hip belt, you will see it described in the review. You can also see more in my video review:

Was it worth it?

If you ask me, the answer is no. As simple as that. I would rather carry 150 grams heavier pack and have all those listed features.

With a bit more weight in the standard series you also have two huge and useful zippered pockets on the front, this is the mentioned feature 7 in the list. I definitely would not mind having them in the pack.

So, I am not sure what they were doing. The new LT version is indeed cheaper, but it also looks cheaper. In any case, these packs are available at REI,  Osprey-US site, and on Amazon.

What do you think? There is a comment box below, so let me know. Thank you for reading.
