I notice at least two people have mentioned taking material, sheets and fleece, and on this I respectfully disagree. Do you have the scissors, soft pencil, needles, pins and entire spools of thread you need to properly make clothing etc?
I would rather have the clothing, bags, shelter items, etc pre-made and waiting for use in my pack. Instead af two yards of fleece a set of fleece including socks, gloves and beane neatly vacuum packed so they stay dry and dust free.
This is JMHO on the matter.
