Osprey Aether Plus 100

rated 2.0 of 5 stars
photo: Osprey Aether Plus 100 expedition pack (70l+)

Mediocre build quality. Mediocre to good carrying comfort.


  • Weight
  • Many smart features


  • Usable volume is 80-85 liters. NOT 100.
  • Carrying 24 kg produces sounds giving the impression it will tear or break.

I did a 133 km in mountain ranges in Norway with this back, carrying  24 kg with the backpack. Never again.

This is not a backpack for carrying more then 17-18 kg. If you carry more, the carrying comfort is very questionable. When I lift the bag it makes sounds as if it is going to break, split, or tear. 

I don't understand where the good reviews come from. This is one of the worst backpacks I have had until now. But I am spoiled. I use Norrøna Recon Syncroflex, a backpack designed by the Norwegian, Swedish, and Finnish army, which has a maximum weight rating of 67 kg.

I am sorry, I have higher expectations, and I don't think this is a backpack for two weeks in the mountains with 24 kg, walking in difficult conditions.

I find it rather disappointing that Osprey is lying about the volume of this bag. By no means is it possible that this is 100 litres. I heard the 100 litres is reached when adding the built-in day backpack. But that is cheating. I wanted a 100 litre backpack, not two backpacks with a total of 100 litres. Smart marketing, but dishonest and unethical.


3 weekend hikes.
1 hike 133 km.
