We kept hearing the same question from buyers: Is there a tumbler that keeps water hot enough to burn your tongue—even after a six-hour meeting marathon?
Now there is.

Meet our new Polar Series vacuum insulated tumbler. Powered by next-gen high-vacuum tech, it locks in temperatures above 65°C for six full hours. Not just lab-perfect—production-line consistent.
Weight? Just 280g. That’s 18% lighter than our previous gen. One sourcing director from North America put it this way: “This is the least stainless-steel-feeling stainless steel tumbler I’ve ever held.”

Samples ready. First bulk order lead time: 45 days.
