The Optimus (H)EAT Insulation Pouch is the perfect solution for eating outdoors. Its unique design keeps your freeze dried meals warm 25% longer when used with a food pouch or cooking pot. Plus, the (H)EAT Insulation Pouch has slip-in side pockets that allows you to eat directly from a food pouch - without burning your fingers. The (H)EAT Pouch works with all brands of freeze dried food pouches as well as the Optimus Terra Weekend HE and Solo Cook pots. What a great idea!
