MYOG Cosy Pouch

As I said in my analysis of the kit I used recently in the Black Mountain, Brecon Beacons National Park, although I like Fuizion Food meals, the 10-12 minute rehydration process leaves the food less than piping hot. Still warm enough, of course, and very pleasant but I want hot food when I'm cold and ravenous. So I had a thought - what about a slant on the pot cosy principle - a food pouch? I am not the first to think of this - Robin Evans has also done it (as, I am sure, have many others).




So I duly went along to B&Q having done a little bit of surfing research and come up with this - 4mm multi-purpose aluminium thermal foil with an R-Value of 1.46. Just short of £12 for a 7.5m roll (600mm wide). That's a lot of cosy pouches! I cut off around 430mm and cut that 600mm wide piece into two 430 x 300mm pieces. The judicious application of some snips here and there to allow a rectangular base to accommodate the base of the Fuizion Food pack when full of water (and create stability) and duck tape to join everything together and hey presto - a 19g cosy pouch. Forgive the workmanship - with more time, the folds could've been neater and the tape cleaner but you get the general idea.






The logistical benefits are simple - continued cooking due to the heat retained in the pouch saves fuel and thermal insulation properties keep the food warmer for longer. It's simple but, I hope, effective. It's certainly cheap and light. And I now have enough foil for around 28 more pouches or a few winter sleeping mat groundsheets...

  1. love it, simple but effective.
    The only downside now to Fuizion Foods is the depth of the bag. (or maybe I need a longer spork)

  2. S2S do a long handled spoon which I use and find to be excellent.

  3. As you say, a roll of insulation makes a LOT of pouches and pot cozies.  And if you really want to improve the finish buy some aluminium tape instead of the duck tape

  4. Ah, good idea. When there casualties and I need to make more then I'll do just that - thanks.
