There is one sure method to carry water or a liquid no matter how cold it gets. We discovered the merits of Bota Bags for carrying 1 to 2 quarts of water when deer hunting in the north woods of MI. I remember one trip in Dec when the temps hit -30 degrees. Nothing else worked.
We fill them with warm water and carry them under our coat. Body heat keeps them from freezing. It is silent, no sloshing noises, and it gets smaller the more you drink. It conforms to your body shape, nothing to poke you. The design is centuries old and derives from Basque goat herders in Spain.
I'm thinking it might make a good way to bring your wine to pot luck dinners at Egg Rallys. Nothing to break, spill, or carry in your hands. Hmm...
