If we are talking about the same thing, I just used duct wrap and duct tape for my pots. Worked like a charm but I'm sure that it's insulation value is less than what ST used below. Just my two cents.

When I made mine I just cut 2 pieces of Reflectix big enough I could fit my largest pot inside ( 2 qt)
One piece I made about 4" longer (flap) so I could fold it over. I used some self-stick Velcro for the flap.

I didn't use any tape to put pieces together. Instead I bought a small tube of Silicone GLUE/sealer and applied a SOLID U shaped bead around the longer piece and then mated them together and put a cutting board on top with a weight and let dry overnight.

I just roll it up after using an secure with a cord.
You could fold it too if that's easier to pack.

Another little tip is when your bringing the water to a boil, and your adding ingredients to a pot, some recipies/packaging tell you to add your ingredients AFTER you get the water boiling.

I don't do that. I add ingredients to cold water and stir it occasionaly as it heats to get everyhting dissloved AS the water gets to boil. Then stir vigorsuoys and put in cozy.

I find at least for the meals I make you get less clumping and a more uniform 'doneness" if that makes any sense to you.

yes pictures would be good
there's a video of the guy making one on the antigravity.com link mentioned below.
might go without saying but not all aluminum tape is manufactured equal. some are better rated to handle heat than others...the one i picked up is rated 350+ deg.

Does anyone have any pictures of these Magic Cozies?

Yeah, at the menard price i could cozy a whole hammock, but will stick with cookware. 
i'm pretty careless about fuel consumption at times. that ought to change, need to be better.

From the Antigravity DYI pot cozi list:
(1) 8″ x 25.75″ piece of Reflectix® for the perimeter of your cozy
(2) 8″ x 8″ pieces of Reflectix® for the top and bottom of your cozy = $11.95

Menards you get 25 sq ft for $11.39 

I made my own cozy out of Reflectix that I could slide a 1-2 qt pot into. If you want to do the individual food pouch route I still think putting pouch in small pot then cozy is better than those stand alone pouches which I bought and now regret I did.

IF there is a difference in the two Reflectix you'd need a micro-meter to tell.


Problem is you need to keep pouch upright or you end up with mess. I found the pouch in pot a cleaner way to go.

I also went a little further on the insulation side.
Once the pot is in the cozy, I set it on a piece of Thermarest pad I use around camp, fold over and put a rock on each end, sort of a pouch within a envelope.

Leave in about 20 minutes and your meal is piping hot. I only stir it once really well when I add the hot water and once again before I eat it.

Saves a lot of fuel not running your stove even on low simmer.

I don't use pot cozys but would like to give em a try.
any opinions either way out there?

wondering if this menards reflectix: (You need to Login or Register to view media files and links)
is the same as antigravity reflectix:

looks like it.
