Clif makes some great tasting stuff and being tasty and palatable is important. Works well if you are doing something active like carrying your BOB as you trek to your bugout location or simply run away from what is spewing from the fan. With a Clif bar and a couple bottles of water I can ride my bike 50 miles.Clif bars
Is the datrex stuff any good?
Ever thought about just making your own? Oats, honey, jello gelatin (your fav flavor), powdered milk and some water. Food saver em and call it good. If interested, I can PM you a recipe.
