What exactly happened to them? I’ve had good luck with the brand, my wife has bought a lot of their cups (she gave me that one). I also have some of the old can coolers I won in a contest at work 10 years ago and those things are amazing, rock solid and really keep a can cold.

They all lost the vacuum that acts as the insulator and were functionally just metal cups from then on. Wouldn't keep anything cold any longer than a normal cup would.

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.
