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

Think you said it best in your post - you need a Thermos.

As in an actual "Thermos" branded one.

I got one of their pint sized food flasks with a folding spoon and screw on cup/lid cover that's so efficient I've got to make my coffee the night before if I want to drink it in the morning, or add cold water if I forget, otherwise it's only cool enough to drink about 12h later.

Those old vintage ones can keep coffee at boiling temperature for most of a work day.

Even the newer fully metal ones are solid (pun definitely intended)

I just looked up the food flask design and I quite like that.
