>>2158323What are you going to do with it? What time of year and in what area? How long? The more you know, the less you carry. It might also be a good idea to wrap your head around the concept of having multiple bags. I am running a hydration carrier with a 100oz bladder and 7 liters of storage and a sleeve that I can stuff a poncho in. Plenty for me here in PA during most of the year. I also try to carry some small gear on my belt and leave as much as possible at home.
