Re: What is the best thermos on the market?
TB,
About ten years ago, I regularly was taking some high dollar donors out on birding trips and got tired of ending up in the boonies with cold coffee and tea for them in the winter. So, I finally went out and bought one of every single kind of "thermos" type container I could find. I ended up with 18 if I remember correctly. Only those with stainless steel liners were considered.
I filled all of them with boiling water and put them in my fridge overnight. The next day, took them out and compared.
1. The stand out winner was the floating model of the Thermos brand. They also make Nissan brand fwiw since you liked that.
Here is the model that won. The shape has changed to a bit narrower and longer than when I tested it, but this is essentially the same.

2. The worst performer was the top of the line Stanley all stainless steel one, which is what I was using at the time.
3. In this product area, price does not correlate to results.
fwiw - if you want a hot beverage on very cold days, use hot tea made with boiling water. The water will start off at 210+ which gives it more heat to lose. Coffee from most coffee makers comes out at 140. McDonalds' coffee is 160+ F depending on the store.
Two 1 liter bottles will stay hotter than one 2 liter bottle. Always fill it to the very top so there is no air gap, and they will stay hot for quite a long time.
Hope that helps.
