Reviewers like these things about 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.

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.

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).

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.

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.

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.
