Post Edit - March 4, 2012
I have added a new cozy template at the bottom of this post. I feel this new template is even better. It allows you to make two cozies by cutting a 23 inch piece off the whole roll of Reflectix. Then cut it down the middle and follow the instructions on the template. If you have any questions, feel free to comment below.
Hey everybody! Got a great project for anyone looking to keep their dehydrated or freezer bag meals warm while in the backcountry. I know most of you know what the acronym MYOG means, but for those of you rookies to the world of GEEKDOM...it means; Make Your Own Gear. We will have quite a number of MYOG articles in the future because much of the enjoyment of being outdoors is that you don't have to spend loads of money to get outfitted. In my opinion, some of the most rewarding aspects of backpacking is gearing up and being creative and resourceful with your equipment {off soapbox}.
OK, with all that said, one of the challenges eating in the backcountry is keeping your dehydrated food warm while it rehydrates. After you add boiling water to your meal and you seal up the bag, you've got to wait around 10-15 minutes before that meal is ready to eat...what to do. If you leave it sitting out it gets cold rather quick and the food never does really rehydrate completely. Come on now, we've hiked 10 miles in...lets do this right, I'm starving! Some of the more creative options we have utilized are:
- Placing the boiling hot bag of food into a jacket, coat or worse...pants (while worn).
- Nestle the boiling hot bag of food around your down sleeping bag.
- Bury the boiling hot bag of food in the ground and then cover it with dirt, twigs, pinecones, etc.
Well, the latter is a bit of a stretch, but the others are realistic options- just not good ones. Taking the risk of spilling that gourmet serving of spaghetti or Ramen all over your sleeping bag, jacket or other unmentionables is not a good idea, nor is it necessary. Enter the COZY. Some genius came up with the idea to utilize a small bag to insulate the food while it does-its-thing! Love it. Simple and cheap. The internet offers many sources for making your own or some people will sell you some all ready to go. I decided to take you on my journey with this project and hope that some of you may find it helpful.
Disclaimer: OAU's legal team advised me to be sure to let others know that neither OAU or any of it's staff, can be held liable for any bodily harm that occurs while attempting to construct this project or any others listed on this website. Choosing to attempt the construction of this cozy leaves you, and only you, completely and wholly responsible for any and all outcomes associated with manifestation of the emancipation proclamation...blah...blah...blah.
That was fun, always wanted to do that. OK, here we go:
First you'll need to get a few supplies. The material of choice for insulation seems to be a product called "REFLECTIX". Reflectix is basically like the thin bubble packing material covered on both sides with foil. I found this at the local hardware store, Lowe's to be exact. The problem with this stuff is that it's actually used for insulation jobs in a home, hence the large rolls. I got the smallest roll available but, it still runs about $15.

That's good and bad...the good is that you can make cozy's for the whole neighborhood, the bad is that you have to pay more money than you should for a small cozy. The same problem exists with the aluminum tape that you also need to pick up. It runs about $5. Again, enough to tape the whole neighborhood! No doubt it's a bit expensive up front, but if you have other friends that you backpack with, there will be plenty for all. Now, just get a measuring tape and scissors (don't start running! -that's why we had to put in the disclaimer).

I've included a template that I made that worked well for me. Feel free to adjust as you need and my design is in no way the best way...it's just my way.
These measurements will allow a standard quart size Ziploc bag to fit inside the cozy. You may want to alter it slightly to your own needs. I don't like to have the Ziploc sit so far into the cozy that you can't reach it or that the Ziploc gets all covered in food as you eat so you have a mess when it's time to zip it up (clean up time). If you would like to have the bag sit further into the cozy, just make the 7 inch depth measurement a little deeper. This material is so easy to cut and work with. Just fold the two sides in and run some of the aluminum tape along the seam and then along the bottom. Here's a photo of the tape on the seams and a shot of the quart size Ziploc nestled in it's new home...ahh...nice and cozy!

Not too deep so that I have to dig for the Ziploc bag
Now were almost to the finish line...once you pour the boiling water in the bag, seal it up and place it in the cozy. You have a couple of options to keep the flap down. The easiest is to just fold the flap into the cozy. You can also buy some small adhesive velcro strips. Attach one to the flap and another to the cozy. Simple! Don't forget that the cozy also makes a safe, convenient way to hold onto your food while you eat it.

Last but not least, no self respecting nerd would dare enter the outdoors without first seeing how much this contraption weighs!

| almost nothin'! |
Only 1.1 ounces! Not a bad price to pay to keep your food toasty and your pants dry! Hope you found this helpful if you were looking to make your own cozy.
