I've been using this bottle for a few weeks now and the borosilicate glass really does feel sturdier than my old plastic one—no weird taste either. It’s great knowing I’m cutting down on disposable waste just by carrying it around.

The borosilicate glass is noticeably lighter than a standard steel bottle, which makes carrying it all day a breeze. I’ve already cut way back on plastic waste since switching to this.

I've been using this bottle for three weeks now and the wide mouth makes it so easy to add ice cubes. The borosilicate glass feels substantial without being too heavy to carry around.
