My pack weight for a 3-5 day trip is 12-18 pounds That includes 2 litres of water at the TH. I generally keep 2 litres of water on me at all times. I try to keep the food down to about 1.5 -1.75 pounds a day, less if it is possible. I hate carrying a ton of weight in food, but by the end of the 2nd or 3rd day its not so bad.
