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


incredibly inconvenient
Imagine sitting in the corner near the plug with your weird resistive heater waiting for the water to get hot
Also, things get pretty heavy when you have a 4 hour daily railway commute. There has been times when I didn’t take a bottle of water because it hurt my back
So I’ll just stick to carrying grounds and buying hot water. It costs practically nothing compared to my current habit of buying coffee which is a huge hole in my budget
