Freezing water bottle

How do you keep your water bottle warm when you ride in the winter?

Either start with warm water (I have even tried hot ribena in my water bottle), or there are some insulated bottles available, like this:

I know it says it keeps cold drinks cool, but it will work the other way round too.

I like that. Nice and simple. I was thinking about wiring a small immersion heater into it. Warm water in an insulated bottle is much easier.

Don't bother - the Polar insulated bottles don't really work to keep stuff warm too long - I tried it out. I've taken to just putting an insulated coffee cup in my bottle holder. It has a sealing fip top lid so it doesn't slosh and it can be used on the go. It will keep liquid warm for about 1/2 hour and not freezing.... for several hours - in other words, its not as cold as the stuff in my regular bottle. I'd really love one of these, but I don't have 12 inches of space anywhere on my frame

Now there is a 500ml version of this bottle that is only 9 1/2 inches tall... if TE were to get some of these made up with their logo I think I'd be pretty quick to buy one

I love love love the Nissan Leak-Proof BackPack Bottle to keep my coffee HOT. I never thought of it to keep water from freezing, but it sure would work. It even has the ridge for the water bottle holder and I find it works great on a bike. (interesting, since that isn't its intended purpose). It has a really great flip top lid that makes drinking on the bike, then resealing easy.
Can get it from Sweet Marias, I'm sure from other places as well.

not cheap, but truly works for coffee anyway.
I gave one to a friend for Christmas last year. Her complaint is that it keeps her coffee too hot.
