I still bring along my cozy..old habits die hard I guess. That said, I did make a fairly interesting discovery recently. On our recent sub-freezing trip, we had to find another cozy for my gf. Normally, I buy mountainhouse meals, repackage the contents into a freezer bag, and throw out the original mountain house bag. However, we saw these new vacuumed sealed "pro-pak" mountain house meals-the portion looks to be in either the same as their old single serving size, or maybe a bit more. They are def smaller than their double serving sizes. However, the bag is large enough to accommodate a zip-lock repackaged double serving meal. Anways, we kept one of these packages, cleaned it out with soap and water, and used it as our 2nd cozy. Best part, it weighed .6oz, is reusable, takes up zero space since it's flat/rollable. It was actually lighter than my own after-market cozy that I paid 10 bucks for. Also, there's no doubting its effectiveness, as this is what the meals were originally intended to be cooked in. I'm thinking about ditching my normal cozy for one, as it's essentially free with the meal itself
They look like this:
I believe the normal 2 serving bag weighs more, so be sure to look for the "pro-pak"
I also round the corners off with scissors because I'm paranoid that any hard pointing edges will damage my UL gear. (I do the same with platy bottles)
