5.5 lbs seems like alot (about the same as my bombproof CampTrails pack). How much weight are you carrying typically?
That's hard to say... I'm not an ultralight, although I try not to add excess weight if I can help it. I noticed the 5.5 pounds as well. The last over-nighter I packed 40-50 pounds - was carrying water and some of the "group" weight. My intention would be to only use this pack on backcountry camping (more than 1 night out) as my MountainSmith daypack is very well suited for one night out backpacks.
