Hey all...I'm wondering if anyone knows of any 1 liter size insulated bike bottles (like a Polar bottle), or some other sort of 1L insulated bottle that will fit in a standard bike bottle cage. I've done some looking with no luck.

I'm looking to add water capacity for longer, more remote rides...it's a choice between a 3rd bottle on the underside of the downtube, or carrying a water treatment filter. My preference is for the 3rd bottle.

It doesn't need to be a squeezy-bottle...I'm OK with refilling the bottles I'm actually drinking from, but my preference would be for it to be insulated. I can't stand lukewarm water, if I can avoid it.

1L Hydro Flasks are too fat...hoping someone out there has a good idea.

Thanks!!
