I used this one for my coffee every morning

(Mine is a 20oz. Not sure why the bare metal one pictured in a studdy 12 oz)
Works great. It's normal water bottle sized so it fits in a standard bottle cage.
Has a variety of lids that work with it. I go with this style...straight screw on/off. No sip straw. No leaks.

I used it in this style bottle cage with the plastic bumpers on the front that 1) keep the bottle and cage from scratching each other up and 2) let me bend the cage a little so make the bottle a nice tight fit that doesn't vibrate or wobble.
I have it in unpainted metal so the paint doesn't scratch off, but other than that...this one.
