Different people are going to want to carry different backpacks. The Sirrus is made for the casual hiker and its design is specifically created to accommodate those in need for more comfort. It's perfect for hikers who want to easy the stress off their back and enjoy the outdoors as it should be.

The Stratos is for someone who doesn't mind carrying a bit more on them. It's certainly going to be much heavier than the Sirrus but it gives you more room for the things you're going to want to bring. Buy it if you want more space.

Treeline Tales

Ventilation is very good, a lot of airflow between back and pack. Osprey’s tagline The wind on your back’ holds true. Therefore the superlatives have to stay in, this backpack deserves it.
