We are crazy about these bkr glass bottles. It’s so hard to remember to drink enough water, but somehow, since carrying these around is actually a pleasure, we’ve actually been hydrating as we should. The silicone sleeve means it’s not likely to break, and the glass bottle means you don’t have to worry about all the things you worry about with plastic. And it fits within most cupholders. Yes, the price is a little high ($28), but if you calculate how much you spend on bottles of water, it is a worthy investment. And it’s so much better drinking out of glass than out of stainless steel.
