Thanks for such a comprehensive post, Arn.
The thing is, I'm on a limited budget (like many) as a grad student, and need a "do-it-all" pack. Something that I can take as a weekender, as well as extended trips on the PCT, JMT, Grand Canyon area, packrafting, etc. This is the main reason I'm looking at the 65 instead of the 50. Though I'm still torn the size. What are your thoughts on the difference between a 50L pack and a 65L?
What are your thoughts on the pack as an all-arounder?
