Here's what the reviewers think about the Osprey Exos:

Reviewers like these things about the Osprey Exos

  • Osprey Exos has been the top pick as the best lightweight backpack and it comes with different features. You can even go lighter without sacrificing features or comfort.
  • Though it is a bit heavier than most ultra-light packs, most of them are more stripped down and frameless. If you are in search for superlight pack but don’t want to go with frameless model, Osprey Exos is the best choice. It still features comfortable shoulder straps, a frame, and robust waist belt. Though it is slightly heavier with these features, it is still very comfortable as compared to minimally designed packs.
  • It is fairly simple to use and has a lot of great features to make your backcountry tour more fun and enjoyable at minimal weight.
  • Exos is literally very comfortably, while considering its low weight. Though it is not as comfortable and supportive as other packs, it is also a pound less than others.
  • On the waist belt, fabric is very comfortable even with some clothing on.
  • On humid days, this pack is cooler and well ventilated with the space behind back panel and perforated shoulder straps to keep you cool on your mid-summer trips. So, it is suitable for warmer days.

Reviewers don't like these things

  • Hip belt is not as adjustable as expected and not comes in different sizes.
  • Shoulder strap pockets and hip belt are mesh only. So, they are not made of sturdy fabric.
  • It is not easy to use Z-style side single compression strap.
  • In side mesh pockets, the holster style cutouts are less secure to stow your small items.

Vs Other Bags


Osprey Exos vs Osprey Kestrel

Both backpacks are great for outdoor activities but Osprey Kestrel is considered as more of a carry-on bag and thus can be used as a travel pack.

Similar to the Exos pack, the Kestrel has a thermoformed back panel that improves ventilation.

The Kestrel comes with an integrated rain cover that can be removed whenever needed. You can quickly attach trekking poles to carry them while wearing the bag. This bag is more durable than the Exos, but the Exos is much lighter.

Another notable difference is that while Exos holds water bladder in the interior, the Kestrel pack holds it in the exterior.

Osprey Exos vs Osprey Talon

Without wasting time on general features that make Osprey outdoor packs the leaders on the market, let's see how similar or different the Exos and the Talon are.

Both backpacks have an excellent suspension system but with slightly different features. The suspension on Osprey Talon has more comfort and breathability attributes and is built with metal wire and backed by foam.

The Talon has bigger pockets: stretch front mesh pocket, pockets on the straps, 2 water bottle side pockets. The hood on the both packs is removable.

The Exos is more streamlined. It may not have fancy pockets and straps, but you can rely on it for hassle-free storage and more comfort.

Osprey Exos vs ULA Catalyst

The Osprey Exos and ULA Catalysts are great backpacks for campers and trekkers. They have all of the features you're going to need for a vacation exploring the great outdoors. Their hip belts and torso harnesses make toting around heavy loads much easier than other backpacks out there.

The Exos is better suited for those who want to do some camping but don't plan on taking too many resting stops. Buy it if you only plan to spend a day or so in the wilderness. For people who want to spend more time outside, you'll want the Catalyst. It offers more comfort than the Exos and a better compartment system.

Osprey Exos vs ULA Circuit

Whatever place you hope to explore during your outdoor trek, the Osprey Exos and ULA Circuit both hold up well in extreme heat or extreme cold. They are roomy, so that you do not have to leave what you need at home. All your stuff will be easily accessible.

The Osprey Exos has your hydration needs in mind, as the back panel sleeve allows you to carry up to three liters of water. This bag is made of tough nylon to handle outdoor ruggedness, which makes this bag perfect if you are mountain climbing or camping.

The ULA Circuit is reliable and highly durable. The provision of the hip pockets is right on target, as these pockets allow you to access items you need while you are walking without having to take the bag completely off your back.

ULA Circuit 0.10 based on 0 reviews

Mitten Camper

All in all the Exos 58 is an excellent backpack. It is fairly lightweight, extremely comfortable, and has some features I've found helpful and useful on the trail. It's a nice pack for people who pack lighter than a traditional backpacker and want some versatility but are not quite in ultralight territory.

Sunrise Gear

The Exos 48 backpack may not be the lightest backpack in the world, but it's certainly one of the most comfortable, breathable, and most versatile light weight backpacks you can buy.

Halfway Anywhere

I really enjoy using the Exos 58, and if it weren't for the obnoxious compression straps (which I am currently removing), then this pack would be perfect (at least as far me right know is concerned).

Dirtbag Dreams

It is near-perfectly designed and sold at an accessible price point. You should get many, many miles out of it.

Ultralight and Comfortable

How can I not recommend this bag? Hiking in it has been a dream – it sits so well on my body that it disgusts me.

The Big Outside

If you generally carry less than 30 pounds backpacking and have modern gear that’s lightweight and low-bulk, or you’re a thru-hiker who wants a pack that offers a quantum leap in comfort and usability over standard ultralight models, you owe yourself a close look at the new Exos 58 or the smaller Exos 48.

Her Packing List

Osprey is a fantastic brand of stellar quality packs – and they come with a lifetime warranty. It’s a great pack for those looking to pack light, but still have room to move despite the carry on size. Best of all, it’s incredibly lightweight and extremely comfortable to wear. Smiles all round!

Overall I think it’s a great value for the money when you’re looking for a lighter backpack. It has filled all my needs and so far I haven’t had to regret having it.
