What's a coozie? smirk I have a cozy with a mylar lining that I use for freezer bag cooking, and anti gravity gear makes pot sets with Reflectix cozies. You can buy or make them easy enough for whatever size ziploc or pot you want to use - a roll of Reflectix and some duct tape goes a looooong way.
