Never had a problem keeping things hot down here in the semi-tropics ...,
You know speaking of hunting in hot areas......if you leave that thermos uncapped in the freezer overnight, and then pour a chilled beverage into it, and close up the thermos when you leave for your hunting area..., at the end of the day you have a cold beverage, if that's more to your fancy.
You could have iced coffee for example.....,
