The cap is simple without excess details and you can drink from any angle pleasantly, like drinking out of a glass or mug. A special structure catches ice cubes and drinks come out in perfect amount.
Double walled stainless steel tumbler, with a vacuum between its inner and outer walls, prevents heat transfer. The foil layer covering the inner wall reflects heat back inside, also contributing to excellent heat and cold retention. Keeps drinks cold under 8℃/46℉, and hot above 65℃/149℉ for 6 hours.
