Think it depends on how much coffee youre making, I prefer French press but typically make coffee for two people

A air layer would work very well for insulation as well but now I'm curious if yetis truly have a vacuum and how much of one.

I bought 1, lost it and bought two more,

First one for 5.99 next 2 for 7.99 each.

I have the Amazon rip off version of this French press and Ozark trail version of this cup, combined cost of 27 dollars and also BIFL
