Mountain House Pro-Pak FoodItem Id: 163778
The Pro-Pak is vacuum packed to give you a convenient stand-up zipper pouch, for a hearty 16-ounce entree from a compact four-ounce package!
Since they're vacuum packed, there's no wasted space for air. They fold up easily, so you can fit more in your backpack. And they won't "inflate" not matter what the elevation.
