My UL 5200 came in at 2 lbs 9 oz.
I also think that when Aron is saying a pack will last several seasons, for most of us that means a heck of a lot longer, if not a lifetime.
As far as fit goes, I do know some big guys that love thier Kifaru's. At 5'11, 190 I don't qualify.
I am not going to get into a debate on whether UL gear is the best choice for someone. I only know that for myself, I will always go with the lightest gear that provides me with the leval of performance I want.
