my partner and I love our wide mouth stainless steel kleen kanteen bottles (one TK Wide and 2 very old classic styles) - they do get dented when dropped but they still insulate without leaks or drips and the no-plastic-touching-the-liquid-including-the-cap and insulating for hot and cold is great.

I like to put a silicone wristband/bracelets (often given out for free to promote events, like the yellow "live strong" ones that were popular a while ago) around the bottle to add some protection and grip!
