Freezer bag DIY cozy on 04/11/2012 23:51:06 MDT Print View

I made a cozy for 1 qt. freezer bags from heavy fleece (not the thicker pile).
It has a Velcro closure, is light and very effective.

What is your favorite cozy material (if you use a cozy)?

I've been using washed Mountain House bags w/the the corners trimmed smooth to avoid puncturing my food bag. UL and pack smaller than any other I've used.

This is some reflectix-like bubble wrap I repurposed from an old fishbox. Held together with duct tape, it weighs just under 0.5 oz.

bubblewrap mailing envelopes on 04/12/2012 08:21:53 MDT Print View

I last used a modified mailing envelope that has small bubblewrap. They are available with smaller bubbles in the smaller envelopes. Those thinner bubbles work well enough, long enough, for the foods and temperatures on my hikes.

First, I bought Reflectrix and it worked too well for me. The food stayed too hot for too long, with the first bite burning my mouth when I was very hungry. For winter temps, or for more people than a solo hiker, reflectrix could do well.

Sounds like I'm suggesting thicker cozies for colder temps--what a concept--I could try that on my sleeping gear too. ;)

3/8" CCF on 04/12/2012 13:54:32 MDT Print View

I make my cozies from 3/8" closed cell foam I get from an upholstery supply company (UFO in San Diego).

Works MUCH better than reflectix-like bubble wrap.

Ike's method works best for me. It works as a cozy, and then I stick it underneath my sleeping pad overnight for extra insulation there.

Another Freezer Bag DIY Cozy on 05/29/2014 21:05:16 MDT Print View

Freezer bag cozy made from insulated grocery bag ($3.00 from Thrifty Foods, Victoria, BC). Metallic layer on the inside. Tough (unknown) material in the outside. Material is about 1/16" thick. I sewed the bottom and side edges. Top edges on the flap are sealed with coloured duct tape. Velcro closure. Total weight -- 35g. Dimensions of the main rectangle -- 7.5" wide x 8.75" tall. I haven't tried this one yet but I've used this material before on a pot cozy. It keeps dinner in the pot hot for 45-60 minutes while it is rehydrating.FrontBack

neoprene on 05/29/2014 22:47:02 MDT Print View

I use a Fosters can pot and a cozy for that I made out of a wine bottle cooler. I haven't got pictures of what the wine bottler cooler started like but after some careful cutting and dodgy sowing I ended up with this:homemade cozy

It is 3mm thick and weight 26.9g (almost as much as the Foster can itself :( )right on 1 ounce and works VERY well!! Of course I want lighter but it works so well and it is tough so I might keep it till it dies.

windshield sun reflector on 05/30/2014 06:42:57 MDT Print View

Just made a new cozy this week for my new Caldera Keg-F setup, used reflectix-like material from a windshield sun reflector. Designed it to work with the caddy that comes with the kit. Cozy is 0.63 oz.
