This way I have insulation for slow drinking and can also set the cup on the stove to boil a small amount of water.


That soundl like the solution, especially when eating food and your pan is greasy. Perhaps a neoprene sleeve cup for me.

Ill be honest and say the double wall cup is not covered and even in bad conditions doesn't cool fast.
