I just took a look at the 3-day gear list on the Hikelite web site. The food list was 28 ounces. Even if you do not count breakfast on Day 1 and dinner on Day 3, (2.33 days in reality for a 3-day trip) that is only 12 ounces a day! The site fails to list the total calories in that ration. I doubt it is more than 1800 calories per day! I am a small person and loose weight on 1 pound a day- I usually take 1.3 to 1.5 pounds per day for about 2,500 calories per day. Any descent sized person who is going to rigorously hike for 3 days needs about 2,800 calories per day.

The Hikelite ration should be called the "3 Day Hunger Ration"

It is deceptive to present a ration list such as this and not include calories and nutritional content.
