Hi Hikin_Jim

The British Ration Pack is pretty heavy at around 1600 grams. Its not lightweight but there is enough calories for me for about 2 days. I would say that the packaging wastage is probably around 100-120 grams. At 4000 calories for 1500 grams this works out at 266 Kcal/100gms. Not to bad considering no addition water needs to be added to the main meals, but this can be improved by adding a few freeze dried main meals such as the Reiter main meal packets and Breakfast Oatmeal Sachets (Scotts Porage Oats) for multiday hikes. The breakfast meal should actually be considered a main meal. The meals can also be eaten cold just like the MRE. The cost of the ration pack can be had locally for about £5 or $10.
