Osprey Stratos 24 Pack Review – What Everybody Says Is True

[wp-review id=”1267″]

I bet you will immediately agree with me on this one.

Life is much more difficult on the trail without a good hiking backpack.

Finding a GOOD rucksack is not easy, though. In fact, that is why I created this Osprey Stratos 24 pack review – to help you understand whether the hype about the Stratos is justified. And after spending hours testing and researching now I know why so many people are crazy about this daypack.

If you have owned a backpack or two, you probably know that often one thing works at the expense of another, especially if it is a cheap brand. For instance, I had a pack that was super lightweight but not so comfortable because the shoulder straps were rubbing my back.

I am pleased to say this is not the case with the Stratos Osprey model. The backpack performs equally well no matter if it is for adjustability, fit, storage or durability. Believe me when I say that its overall comfort is unmatched.

I’ll start by making a small, yet important precision. This review is about the updated Stratos model (2017). The previous one had two unadjustable sizes – small and medium while this one is better. It allows a much more tailored fit thanks to the adjustable torso length panel on the back.

It would be difficult to find someone with a keen interest in hiking who doesn’t know that Osprey is a high-class brand. The name is a synonym for quality for more than 40 years. And there’s surely a reason why. They stand behind their products and back them up with a lifetime guarantee.

As some of my fellow hikers like to say - you don’t purchase a backpack from Osprey. You are rewarding yourself with an Osprey. It’s a valuable investment in the quality of your outdoor life.

Having owned several packs from the brand, I have to agree. In fact, I'm also a proud owner of the bigger model - Osprey Stratos 50. You can learn more about my experience with it here. I was very intrigued to learn more about the fairly smaller Stratos 24 too.

The Stratos series combine great comfort and usefulness thanks to some amazing features. Here I mean the famous AirSpeed™ ventilation system and the already mentioned adjustable torso length panel, among some others that I’m going to describe in a minute.

Before that let’s see who will benefit this pack at the most.

Who Is This Backpack For?

First, it’s important to notice that the Stratos series are designed for men.

The women’s equivalent are all models from the Sirrus product line. I found great that Osprey cares enough to create models that strictly comply with the body specificity of both sexes. Those differences matter a lot.

Being a daypack with a volume of 24 L or 1464 cubic inches, the Stratos 24 works best for 1-2 day outdoor activities:

  • Nature walks during the weekend
  • Hiking
  • Short backpacking trips
  • One-day mountaineering
  • Ultralight backpacking

You can even use the Stratos for commuting if you’d like. However, I don’t like doing that because it shortens the life of my pack. I strongly believe that every rucksack has to serve its purpose and this Stratos model is best suited for hiking.

Now let’s check out the features.

Overview of Features

Owning an Osprey pack, you have to prepare yourself for a lot of features, even for a compact day pack. Hopefully, none of them are superfluous. Every mechanism, strap or a pocket is there for a reason – to make your walk easier and more comfortable.

It’s true that sometimes you don’t know how to use all the features in order to achieve the best possible fit and carry. Don’t worry, there’s a user manual for that but I will tell you about it in another section of this review.

Now, watch the video below in which my friend Base Camp Chris meticulously depicts the pack.

What I personally like a lot about the Stratos 24 is the well-structured, lightweight frame. It follows the curves of your body so you can imagine the comfort I felt when I first wore it.

Now, please follow me and let’s jump to the details.


Good news!

You’ll be able to take the Osprey Stratos 24 as a cabin luggage. The pack’s dimensions will fit the carry on requirements of any airline – 22” x 12” x 12” or 56 x 30 x 30 cm.

There’s enough room for spare clothes, food, water, and any kind of gear you might need for a day hike. You can also use the external storage capacity to take voluminous hiking supplies. Don’t expect too much, though -it’s a daypack after all.

All in all, you can carry comfortably 10-25 lbs of gear. I don’t recommend going beyond because the pack won’t hold it the way it should.

In the next paragraph, I will share my impressions about the materials and the weight of this buddy.

Weight And Materials

Honestly, I expected the pack to be lighter for its size and volume. Don’t get me wrong – it’s not heavy at all. Still, I’ve had backpacks lighter that this one.

As an example, if you read my Gonex 35 L backpack review, you’ll notice that it is lighter than the Stratos – only 2.3 lbs or 1.07 kg for 35 L!

Thinking about it – it’s probably because of the thick padding and the reasonably rugged materials that the Stratos model has. For me, that’s a fair trade-off for such a tiny difference in the weight.

To get straight to the point, Stratos 24 weights 2.76 lbs or 1.2 kg. When fitted well and thanks to the ventilated AirSpeed™ trampoline back panel, you won’t even feel it’s on your back.

When it comes to the materials, no upgrade here. The fabrics used to make the pack as durable as it is (and believe me – it is) are 210D HT nylon. The bottom is even reinforced with a higher denier – 420D HT nylon.

Overall, the backpack is hard-wearing. I haven’t used it for more than 3 months to say more but I have heard great feedback from fellow hikers.

The time has come to mention what I like (and don’t like) about the comfort.

Usability And Comfort

This is where the Stratos and the Sirrus series excel.

To repeat myself, I’ll mention one more time that the Stratos is amazingly comfortable.

When I first put it, it wasn’t like that, though.

Somehow, the top of the pack was touching the back of my neck and it was rubbing my shoulders. It turned out that I needed to adjust it to fit my torso size.

ventilated backpanel

That trampoline suspended mesh keeps the heat away while the padding on the shoulder straps reduces tension and prevents rubbing.

So I used the adaptable torso length panel and moved it a little bit so the pack adjusted to my back, completely following the shape of my spine and shoulders. I have to tell you - it felt like a part of my body!

I mention that because some people wrongly believe that when they put a backpack, it should feel comfortable immediately. Don’t forget to adjust it using all the features and straps. That makes all the difference.

Now, here’s what the Stratos offers in terms of comfort and easiness of use:

  • Unreal ventilation thanks to the well thought out AirSpeed™ suspension system. The sensation of not having a sweaty back on a hot hiking day is just wonderful. Osprey took care of this thanks to the trampoline suspended mesh that stands between your back and the pack. In other words, the pack doesn’t touch your back, thus allowing the heat and the sweat to evaporate easily.
  • Perfect fit thanks to the adjustable torso length panel – this new addition to the 2017 model is very handy because you can make the pack fit to your body with a single move.
  • Long-lasting comfort when carrying heavy loads – that’s because of the thick padding on the meshed shoulder straps that reduce tension.
  • Greater stability of the pack on technical terrains thanks to the chest and hip belts (the latter is padded).
  • Comfortable wear even when the pack is not full – you can use the double side compression straps to shrink it, thus avoiding shift load and unusual hanging.
  • Safety whistle on the chest strap for emergencies that I hope you’ll use only for fun.

The only thing I don’t like in regards to the comfort of the pack is the lack of padding on the chest strap. On longer hikes, it’s possible that it starts rubbing your sternum so make sure to loosen the ends a bit.

Now, I’m eager to present you the storage abilities of the Stratos 24 so continue reading.

Storage And Compartments

My wife recently bought an Osprey Skimmer 28.

She loves everything about it except the fact that it lacks enough pockets and separate compartments.

I have to admit the Stratos 24 is slightly better designed in that aspect. In fact, the rucksack exceeds my expectations for storage and pockets, even though many people consider its compartmentalization poor.

Stratos 24 integrated rain cover

The rain cover is stowed in a bottom zippered pocket and you can remove it if you like.

The Stratos has 5 external pockets and I think there’s enough room to accommodate everything you might need even for an overnight hike. You can attach gear on the exterior too.

Keep in mind that you access the backpack from the panel.  

Let’s learn more about all the pockets and storage features of the Osprey Stratos 24 pack:

  • Maximum safety for your essentials that will always stay perfectly dry thanks to the detachable rain cover, stowed in a zippered bottom compartment. The color is green.
  • Dedicated sleeve for a water bladderhydration-compatible, the pack has an easy access pocket on the back just behind the trampoline mesh where you can stow a 3L reservoir. That will help you stay hydrated effortlessly, on the go.
  • Zippered and padded hip belt pockets for storing napkins, smartphones, and everything you’d want quick access to.
  • Under top lid zippered meshed pocket – I like it a lot and I store first aid kit supplies there or socks.
  • Vertical zippered pocket on the front panel – it’s a bit shallow, especially if the pack is full but it allows you to store items that are not voluminous such as gloves, a map or even a t-shirt.
  • Zippered pocket on the top panel for stashing various stuff. I use it to put my phone charger, a head torch, and my toothbrush when I go for a weekend hike. The pocket is roomy and gives you the possibility of putting essentials that you don’t want in the main compartment.
  • Easily carry, access, and secure walking poles thanks to the seamless Stow-On-The-Go attachment system that allows you to put your poles on the side using smartly designed lashing points. Like that, the poles are next to your arm and you can detach and attach them without taking off the pack. Cool!
  • Loop with a bungee tie-off that you can use to attach an ice axe if you go really wild and hike on more demanding terrains.
  • Dual side mesh pockets for water bottles or anything else that might fit in there. They are spacious enough.
  • Internal key clip for securing your keys – unfortunately the clip is weak and the keys slip off easily when you walk. That’s why you might consider adding a carabiner instead.

I think I don’t miss anything. Don’t hesitate to ask questions in the comments should you have any! Now let’s move to an important part.

How To Use This Backpack?

Like already outlined, Osprey is known for designing their products with tons of useful features. If you don’t use them the way you should, you just won’t be able to experience the maximum comfort of the backpack.

What if you want to use them but you don’t know how?

The vertical front pocket is large and shallow. I use it to put my e-book reader.

Luckily, there’s a user manual. It explains every component of the pack and has tons of illustrations. It’s really handy so make sure to check it out.

I’ll just mention three important aspects when it comes to proper usage:

  1. Regulate the adjustable harness so it matches your exact torso length. It is positioned on the backpanel. You need to glide it until you achieve the desired fit after loosening the load lifter straps.
  2. If you want to add a water bladder, note that there’s an external sleeve where you can put it. Again, you’ll find it on the pack’s back. Properly positioning it using the buckled loop will assure a better load distribution.
  3. Don’t forget to use the side compression straps to shrink and tighten the size of the backpack for optimal carry.

Now, I’ll show you some cool alternatives that you might want to consider.


To decide what pack would be best for you, you’ll need to compare it to others.

Here are some alternatives worth checking out:

No products found.

If you want something similar in terms of volume and quality, then consider checking out Osprey Talon 22 L. It’s super versatile, lightweight, and the ventilation system on the back is still amazing.

Should you need a bigger volume from the same brand, then take a look at Osprey Manta 34 L. It has 7 exterior pockets and hydration system included with a 2.5 L water reservoir.

A slightly cheaper alternative from another respected brand is Deuter Walker 24 L. It’s highly ergonomic and has an S-shaped soft edge shoulder straps to reduce tension on longer hikes. The airflow on the backpanel, courtesy of Deuter is awesome too.

If you prefer a budget-friendly pack that you’ll not regret buying, then check out Neekfox 35 L. It’s well worth it and the price is ridiculous for the surprising quality.

A great option for the ladies is the fabulous Gregory Maya 16 L. 



What is the torso fit size of the Osprey Stratos 24?

Is this a foldable backpack?

Does it comes with a hydration bladder?

Can I put a 13" laptop in the pack?

Is the rain cover removable?

How much load can I carry with the pack?

Final Verdict

Not without some minor flaws, Osprey Stratos 24 is a well-worthy all-around backpack.

What most impresses me about it is the unparalleled comfort, courtesy of Osprey. This is achieved thanks to their revolutionary AirSpeed™ ventilation system on the back panel that keeps my back dry even on the hottest days.

The adjustable ergonomic shape of the pack makes it super easy to maneuver with which is crucial on longer, more technical hikes.

In brief, you can’t go wrong with this Osprey pack if you want to invest some bucks in a quality hiking daypack that will last you for many years.

Awesome! I have 2 Osprey backpacks since 3 or 4 years and I absolutely love them. This one really interests me because I’m doing a lot of motocross in the wood and since it has place for water and accessible pocket for phone or other gadgets it is very cool.

I take good note of your review. Thank you!

    Asen - August 3, 2019

    Hi Audrey,

    You’re yet another hiking enthusiast who’s happy with Osprey. Me and my wife we have Ospreys too and we love them.
    I think the Stratos 24 will be perfect for your motocross stugg because it is lightweight and compact, and as you say, with enough pockets. Enjoy!

Jeff Schumn - August 3, 2019

Well written Osprey review Asen. I like the FAQ section before your final verdict. Sounds like their revolutionary AirSpeed ventilation system on the back panel will do the trick on hot days.

    Asen - August 3, 2019

    Thanks for reading, Jeff! Airspeed is something that you should try some day. You’ll love it.

Trekking in (abc) Annapurna Base Camp has always been in my bucket list. Your Osprey backpack seems really light and comfortable.
I had one of my backpack completely torn off in my recent hiking in mustang. Thats was really a pain in ass cause i had fear of losing my neccesiting in the hike.
This Osprey backpacksclooks reliabe and I look forward to buying it. Very good product review.

    Asen - August 3, 2019

    Hi Sujit,

    Sorry to hear about your bad experience with your old pack. Osprey Stratos 24 is surely very reliable as you say and durable as well. I also hope to visit Annapurna Bse Camp one day.

Excellent and thorough review.This review verified everything I’ve experienced owning the Stratos 24. My wife (who has the Sirrus 24) and I hike extensively in the South West US particularly the High Sierra. It is the best fitting and most versatile day pack in its size range I have ever owned. It feels like part of you once you get it adjusted. We use them “rucking” for training hikes loaded with water and duct-taped bricks and they carry 10-22 pound loads just fine.

    Asen - August 14, 2020

    Hi Danilushka,

    Thanks for reading my review! The Osprey Stratos 24 is my favorite backpack. It really becomes a part of your body once adjusted. I also have the Stratos 50 and it’s as good.
