How can I I sheathe a glass bottle to bring it to the gym?

[Rt-Rust1]

I try not to use plastic bottles because of the BPA. So I was considering bringing a glass one but I'm sure the nigga who owns the gym is gonna told me not to bring it because it may be dangerous. So I need an idea to cover it so he doesn't realize it is glass

Why not just buy a canteen or a hydro flask. Any kind of metal water bottle would work.
