No, I wasn't talking about a bike water bottle, just a bottle-o-water to carry around--at work, in the car, places like that.
For bike riding, I stick with my regular plastic bike waterbottles (not nalgene--but the sqeezable kind). I drink the water pretty quickly, and I empty/wash them after the ride, so there's not much time for the nasties to infiltrate. My car and work water bottles, however, stay full alot longer.
When I was 15, I rode my bike through France for a month. Evian and Volvic came only in glass bottles in those days, and they fit in our water bottle cages.
