Recent two month tour which included a 40 degree down bag and a bag liner which got in down to 25 degrees came in at 35 pounds not including daily water. Their was two much duplication between my partners and myself. We found we act most meals cold, between us we had three stoves and pots and pans and gas. The weight gear varied a lot - I came in at 35, partner 2 closer to 50, partner 3 at 70lbs. They had a extra tire and I had tire liners. To much duplication in mechanical gear as well. The biggest difference were bags. tents, and on and off the road cloths. My bag and liner was less than 2.5 pounds, tent was 3 pounds, and pad at a pound at opposite end of stectrum there was 5 plus pound bag , at 5 plus pound tent , and almost 2 pound pad. Several day of food alot by partner varied alot as well. As a diabetic I also carried 5 pounds of drugs and medical testing gear.
