The design and materials of this thermos is outstanding, but if the company still hasn't solved the issue about the lid, then it won't stay hot (36 hours) not even close. The lid is getting hot immediately and it lets out heat. I did make a test against my old favourite thermo, which shouldn't be better at all. It was clear that the lid is letting out heat, much faster than it should. I returned the flask with a hope of, that I just got a lid with a defect, and I could get another one.. but after a Google search, I didn't want to bother with buying/returning another one. That's just a shame, because the design, materials, functionalities like leakproof and the 360 degrees pouring is just remarkable. I hope that You will get the hot lid thing sorted out.

We have been using Kleen Kanteens for years now. We bought them thinking they would be durable, which the flask is. However, the sports cap needed replacement every year. The soft rubber/silicon would tear after a while. Replacement caps are expensive. Also not as leak proof as we would have liked. We are changing to a different brand

I bought a bottle from Klean Kanteen - It's very stable and looks beautiful, but it's unfortunately very expensive. Furthermore it was very difficult to open it. So I bought a different capping from Klean Kanteen, but this was leaky.
