Lightweight thermos

Ended up getting one of these as it appears that it would work great for backpacking which I do all year long.
This morning at 0800, I put boiling hot water in it and measured the temp. I'll check it after 12 hours and measure it again.

No replication? No controls?

You get what you get.
It's very scientific.

Preheating a Zoji with boiling water before filling it with freshly brewed coffee will raise the temp of the coffee and scald your mouth hours later. I'm surprised it doesn't come with a lawyer label.

I bet. I usually do that but just wanted to see what it would do without the pre heat.

Ya'll costing me money. Zoji on the way.......

I wonder if these things are similar to my Contigo? Someone got me this thermos bottle that keeps coffee and tea scalding hot all day, almost annoyingly hot. But fits my truck cup holders perfect.

I got my own anecdotal evidence, I’ve burnt my mouth drinking from mine after having had coffee in it for 6 hours several times

I think what you see for data point number 1 is key. The inside is so thin there isn’t much metal in there to cool the liquid down. The others I have are cooler to start because that liner absorbs so much heat.

12 hours exactly. Pretty impressive.

Almost like magic. The hold up well given how light they are. I've dropped mine multiple times on hard floor and it has survived. The reinforced base is just thick enough.
