Best 1qt cold weather coffee “thermos”?

Thank you to all that posted their experience/opinions! I am always wary of company sponsored tests because the money can get in the way of results.
This forum rocks!

Not sure about the 1 quart, but Hydroflasks work well.

Ok, after seeing this post I dug out my 1982 vintage 32oz Stanley the other day. Not a scientific experiment but I pre-heated it with hot water, dumped it and re-added hot water and closed it up. This was in the morning, in the evening I opened it back up and if it would've been coffee it would've been totally hot and drinkable. I couldn't post a pic but mine has a black handle that doesn't move at all, the straps that hold it on are like large wire ties. So for the price and the size Stanley is probably still a good bet.
