Pictured here is my base pack with no food or water. Everything in this photo weighs 18.3 pounds.
I am happy with it, and I am running out of ideas how to save more weight because I do have a safety margin and I’m not willing to cut out stuff that I feel I need. Add upon this anywhere from 10 to 17 pounds of food per resupply. Water is heavy, 2 pounds per liter. In this pack I have the capacity in empty bottles within to carry 12-1/2 liters of life giving water, so if full add 25 pounds.
I would estimate that for each resupply I will start out with a 40 to 45 pound pack. Some sections that are very dry I could easily start out with up to 55 pounds. The nice thing is you drink water and you eat your food so your pack always gets lighter as you approach the next town.
