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


Zojirushi is the GOAT as far as I’m concerned. No other brand I’ve used has kept my coffee hot for as long as they do.
My only gripe is that they like to over-engineer the cap/pouring mechanism in their travel mugs, which makes them tough to clean.
It’s been awhile since I’ve had to replace one, but if I recall you want to get the plain stainless interior for coffee / tea, as it picks up less staining and odors than the coated interior.
Slightly off topic, but there is a product called Astonish, which is amazing for cleaning travel mugs and other things that collect coffee oil buildup. Its hard to find in the US at least, but can be found on Amazon.
Lots of people recommended Zojirushi in this thread. Will definitely give it a try. Thanks
I noticed when I started using (stick blended) coconut (mct) oil instead of milk buildup just dissolved over time. Would likely work to just soak in hot in hot oil…
I use polident to clean my Zojirushi container.
I’ll have to give that a try, especially if it means one less thing I rely on Amazon for.
