I don't like namedropping brands, but I bought a Sigg water bottle about 5 years ago, cost me 20 euros, it's rock solid and it just works as a container. It could be any other brand really, just anything with a large enough volume that you fill it in the morning and drink from it all day long before washing it at night, leaving it to dry and starting over in the morning. It's a good system.

I do the same, but with a good old glass of water. These are under rated I believe

EDIT: You're right about the glass. I initially misread your comment, my bad.
