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!

Even prettier in person! I love the texture on the bottle and how smoothly the lid screws on. It absolutely makes drinking water more enjoyable. I use it at my desk, at the gym, in the car, at soccer practices, etc., and it's holding up great!

Great mugs, great deal!!
I purchased a mystery set of 20oz mugs. They are beautiful and large! Great quality, do NOT do that annoying thing where the handle heats up in the microwave-a real plus! The selection of designs we received is pretty much what I would have chosen left to my own devices. A+!!

Great design!
I love the enigmatic design of this this mug. Has it been buried in the sands for 10,000 years waiting to be discovered? Quite possible. Made for a great gift.
Gift for my sister in law
She likes beer and climbing mountains. And backpacking the AT.
