Welcome to Mystery Ranch!
Just sent them an email on their site asking about whether they fit those of us who are tough pack fits. My all expense paid vacations from 1976 to 1998 with my rich uncle, Sam, have left me with a strong aversion to external frame packs (ALICE, anyone?).
The two top things in my experience that can make you the most miserable during long range trekking the great outdoors are bad boots and a bad pack. Insects, the elements and theterrain all all a distant second (except those damn "banana" spiders that build webs tree to tree in triple canopy jungles and swamps - ran face first into a web once in the pitch dark, and almost had a heart attack when I felt the web "twanging" as an interested very large spider came to investigate- that is high on the list too).
