What could be more perfect and handy for heating your MRE camping rations than a light, easy to transport thermal cooking mug. Use the carabiner to attach the mug to your backpack and set off for your next adventure! When conditions are too wet or so dry that the fire risk is too high to make a campfire, use Barocook® flameless cooking heat packs. The 13 oz. mug / thermos is perfect for heating food or reheating leftovers. There is no reason to survive on cold food or energy bars. Add Barocook thermal heating to your camping gear or emergency survival kit and have a good meal when you are out camping or riding out a hurricane. Shop today!
