You will own a glass water bottle and you will be happy. Even the TSA allows them.
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/ https://image.nostr.build/19a6a7d44430c390359bdb53180f3f5d3ca7434265434a059847ee95dbe192c4.jpg
