If you should decide to buy the type of ordinary water bottle, there are better ones that are better made. These are better made ones that aren't quite so notorious. These are better to drink ordinary cold water out of than the previous ones. However, do not put the bottle anywhere that the bottle material would become heated (e.g. in car cupholder next to car heater, heated in microwave oven, and other places. It is safe to keep it in its cage on the bicycle during the ride, but not to be left there afterwards. Heating the bottle will reorganize the bottle material and thus could make chemicals leech into the water.

I keep my water bottle clean and in a cool place. I recommend that you do, too.

I don't know about the latest metal bottles. Who knows what could be in the liner?
