Deuter ACT Lite 65
This pack fit great (I'm 6'1, athletic, and used the second-to-highest setting). It was really easy to adjust, and the sleeping bag compartment made it really easy to get to items at the bottom of the pack. The feel was balanced and the padding made me barely notice my shoulder straps.
This was the first Deuter pack I've carried, and I'm definitely a fan now.
