Making the Inner Bag
Take your scissors and one of those thermal bags and cut off the handle and then cut it right up the middle. Tape one of the sides that you cut closed (with the exception of the top of course, see picture 3 on this page). After you have half of it taped, place that inside of the other half of the bag and tape the long side closed, this will also hold the other piece in place and give it 2 good walls and make it doubly thick. When you put the one half inside of the other and after you tape the side, you’re going to have to tape the openings. There are about 4 or 5 pieces of insulation on each wall and we have it twice as thick and there are two walls, so there are about 16 or 20 pieces of insulation so you need to divide how ever many there are by two and tape that many together on each side so the food goes in the very middle. The fifth picture is of the other bag, but if you look at it you’ll understand what I mean. If you’re only going on a short 2 day hike you can just freeze your hotdogs and throw them in this small bag with your already cold eggs and already cold sodas and they will be fine without a freezer pack even, but for longer trips you’ll definitely want to go onto the next steps.
