Okay, just broke the mylar on my Datrex 3600 (coconut cookies) pack. Not bad flavor, but definitely not complete nutrition.
Ingredients: Wheat Flour, Vegetable Shortening, Cane Sugar, Water, Coconut and Salt.

I'm looking at these as a way to increase calories in my 96 hour kit and extend other nutrition sources so the kit will go longer than 96 hours. Plan is to add two Datrex 3600 packs to the food cooler in my truck's 96 hour kit. With the food already in the cooler (MRE's/freeze dried entree's and canned soup), the kit should be good for 10 days +/-. I would not put myself on a Datrex diet, that would get very old, very fast.
