I have been using the standard reflectix cozy that so many people make for freezer bag cooking. It works great, but weighs 44.7 grams. I was pondering my gear last night and my mind settled on the sit pad that Kaboose (MaineBob) came up with. It is just a square of a Dollar Store window shade made of mylar and foam. My 1st square has lasted me 2 states. This thing is surprisingly tough. I have not been super careful with it. It dawned on me that this material might be suitable for a freezer bag cozy. The version of window shade that I use is the cheap one. It only has mylar on one side.
I cut 2 strips out of a new window shade @ 8.5" x 35" to build 2 new cozies. With the foam side up, I sprayed half of each strip with spray adhesive and folded them to create 2 strips @ 8.5" x 17.5". With the joined ends at the top, I folded the glued strip from the bottom toward the top 7.75". I joined the edges with 7.75" x 1" aluminum tape. Lastly, I trimmed the flap to 2" and trimmed the edges to smooth up the irregularities from the imperfect fold and glue process.
Next, I tested one. I boiled 2 cups of water and poured as much as I could into a pint sized freezer bag (the standard quart size that most use is overkill). I removed as much air as I could without burning myself and slid the ziplock into the new cozy. I placed the cozy in a refrigerator and waited 30 minutes. When I removed the cozy, the water was still too hot to touch.
Here is what it looks like. It was hard to get a picture, so I put a cup on the scale and zeroed it and then took this picture with the cozy on the cup. Sorry for the picture quality. My phone takes crappy pictures.
