That's a nice svelte looking pack. What is the ventilation like on your back? Also, it seems like there is uncomfortably little room behind your head. Is there "cup" or indentation of some sort that allows for more clearance than is otherwise shown in that side profile picture?

Vigilguy can answer as well, but I know with my McHale, the two stays that make the bayonet system (which extends the pack up behind your head) are intentionally bendable so you can angle it closer or further from your head as you desire.
