Insulation performance is not overwhelming, yet super product

I have this bottle for some time in operation, both with cold and warm drinks. The insulation keeps a certain amount of time to long, but you should not expect much here zuu. Those who wish to use any inflexible aluminum bottles, is already right here. Otherwise, the quality is just awesome. Have previously had a good experience with CamelBak-Flschen. Hold, do not stink, do not have a taste of its own and there is simply no better closure. A dream would be a 1l-Flat.
