Amazing, Simple, and Light Cozy Cooker - Save Fuel and Time

All you need is some reflectix (or a car sun shade from Walmart) , a sewing machine and some velcro.  You can save time and fuel with this cozy cooker for re-hydrating or cooking meals.  Add boiling water to a quart sized freezer bag with a dehydrated meal like mountain house or a home made meal -put the bag in the cozy and let it cook on its own while keeping it piping hot. Instead of simmering for a long time and wasting fuel, use this cozy while you set up camp or whittle sticks for fun.
