I take a 2 hour commute to school every day. My Stanley thermos, which was gifted to me by my very consumerist aunt, doesn’t keep my moka pot coffee hot for 2 hours.
Although it is a pretty good thermos it seems to be leaking a lot of heat from the metal section near the cap.
Is there any thermos that has every section of it isolated? Like, I shouldn’t even be able to tell if there is a hot liquid inside


Klean Kanteen has worked great for me. Kept tea that my girlfriend and I made at 7:00 too hot to drink at 13:00. And that was at a snowy mountain lake – the time in between was spent snowshoeing up a mountain trail in the middle of January.
Maybe a silly question, but do you preheat the inside of your thermos with boiling water before adding the coffee from the moka pot?
If not, that small amount of coffee would be quickly cooled by the inner walls of any thermos.
I don’t, but I am pretty sure it doesn’t get cooled down by the inner walls as it stays too hot to drink for at least an hour.
Will check out your recommendation.
Preheating makes a big difference
