Frequently asked questions
How does the hiking pack volume work?
It converts nights out into a planning class using a published rule. Map nights out to a liter band and add volume for a bear canister or extra water. The headline is a class such as 20–30, Daypack, 50–60, 35–45, and 65–75, not a vendor ranking.
Is Osprey Talon 22 better than Osprey Atmos AG 50?
This page does not rank Osprey Talon 22, Osprey Atmos AG 50, and Gregory Baltoro 65. Osprey Talon 22 and Osprey Atmos AG 50 are listed because they are real products with official pages that map to different or overlapping classes. The useful question is which class matches your inputs.
