I cannot recommend highly enough having a set of glass bottles[1] at home. Fill them at the tap (or wherever), refrigerate them, take them to the gym, in the car, serve to guests. Point is to have many, keep a rotation going. Has greatly reduced reliance on plastic.

Gyms often ban glass bottles because of the hazard they create when dropped/shattered.

I personally use a hard (i.e. not squeezable) plastic bottle, that I fill with cold/cool water just before use. As long as the water has not been sitting in the bottle for days or in the sun or in a hot car, etc. I don't think there is enough potential chemical leeching to worry about.

Any reason to not use a Yeti cup or similar stainless steel thermos cup?

Wouldn't metal be far preferable? Especially double-walled metal bottles that can hold liquid at a temperature.

They don't break.

I do have some glass bottles as well for occasional use by guests, but when on the go, the popular metal water bottles seem best.

You can often buy milk at a coop in a glass bottle which can then be reused. Most of our beverage consumption is out of re-used milk bottles. :)

In my state it is illegal to use a glass milk bottle for anything other than milk from the dairy that the bottle is from. The law is from many years ago, and so there are a lot old bottles from now-defunct dairies that legally cannot be used even though everyone does.
