Here's how it works: the space between the inner and outer flask wall is evacuated, creating a vacuum (well, a partial vacuum anyway...). In order for heat transfer to take place from the outside world into your cold drink, or from your hot drink to the outside world, it needs nearby molecules to excite. If there aren't many molecules nearby, as is the case in a vacuum, the heat's energy can't easily be passed along, so your drink stays close to the temperature it was when you put it into the flask for a really long time. 

Simply stated, vacuums make great thermal insulation!

Love it

I use this every day now. I haven't used it for anything hot yet, but I use it for water, because I can put one ice cube in there and it stays cold FOREVER. The design is beautiful and it has a texture to it that I actually really like the feel of. After seeing mine, my bf now regrets not getting one when I offered lol

The ultimate daily go to for all your drinking needs

This is seriously worth the price, the quality and design surpasses any water bottle or drink container I have ever owned. It's breathtaking! Very comfortable wide mouth rim, easy to fill with ice. This stays exceptionally cold your ice will not even melt inside. I love the geological chart, the texturized design is so nice to grip and feel. This is a wonderful gift for your friends and family too. These are like no other water/drink canister you have ever owned. You will be blown away with it's elegance. The handle on top makes it super convenient on the go or in the field.
