We have both the Thermos Ultralite Graphite version 0.8L which is excellent at keeping drinks way too hot to drink for extended periods of time...

(It is also exceptionally light) and the older Thermos Ultralite version in the 1L size as well which is also excellent at keeping drinks way too hot for 24 hours or more. Both fit into our water bottle holders, though the Ultralite Graphite verison fits much more easily than the older version.
Both have been taken on tours (the 1L on a 12 month tour) and are bomb proof (so far!)
Camelbak do one, looks ok but I am not sure how good it is: Camelbak Podium Chill Bottle
I'm not certain that the Chill bottle is one designed for keeping things warm - clue could be in the name. It does however stop water freezing in very cold weather well after other water bottles have frozen and it also does stop water getting as warm in the summer/hotter months as it does in other water bottles. I have one and they are excellent bottles.
