Metal water bottles >>>> I previously owned a glass bottle, took it everywhere including to the bouldering gym. I put it down on the ground, someone accidentally knocked it over and it shattered. Never again.
I don't like the taste of metal. I shattered two glass bottles so far, just replaced them.
A silicon sleeve will save it from most accidents. I have several so I can rotate them in the dishwasher.
I have a different brand, but something like this: https://www.amazon.de/Wessper-Motiverende-Tijdmarkeringen-Herbruikbare-Transparante/dp/B0CP9J7CNG/
