I spent quite a few years dog mushing at extremely cold temperatures. Our cut-off for training was 20 below zero, but we could get caught out at worse than that. Many of us had insulated covers made for our thermoses, see below. We had them made for coolers, too, which we used to put hot water in to defrost the next day's meat for the dogs. My thermos went into this insulated cover. It was made by a local company Apocalypse Design, but I think a custom tent and tarp maker or custom outdoor clothing/gear maker could do the same for you. The insulated covers provided for many more hours of warm drink and food.
