Damn I have the same issue. I may need to look into this Yeti cup!Love coffee with my pipe/cigar but hate having my coffee cooling off. FF to buying a Yeti and happy days are here . I usually don't believe the hype of thermo products but this sucker is for real. I FP a 20 ounce cup and an hour later it's still hot and I'm done with my pipe or cigar...as hot as it was when it was brewed. ..gotta love science.
