I normally hike with a G-4 pack from GVP and use a seam-sealed VBL/pack liner inside (dual use). Inside I carry my sleeping bag unstuffed in the bottom and also carry separate stuff sacks for my cookset , food, clothes and essentials/emergency.
So I am taking four color coded stuff sacks, plus the pack liner all consisting of seam-sealed sil-nylon bags averaging .06 ounces each with the exception of the pack liner/VBL at 4.8 ounces.
Just wanted to find out what others are using for their systems and organization ??
