The concept behind the Yeti Rambler Tumblers is simple. They made a rugged stainless steel tumbler that has a vacuum sealed bottom so there is no heat transfer from the inner wall to the outer wall. This is not new technology and it has been proven to work. What Yeti did right was take this technology, make the right size tumblers, made them strong, and added in a sturdy cover that is easy to clean.

What We Like:
You don't appreciate ice cold beer or super hot coffee until you start using the Yeti Tumblers. These things keep beers so cold. We are convinced that beers get colder when they go into this tumbler. It can be a very hot day and your beer will stay cold even in the direct sunlight. It is crazy. Crack a beer. Fill the tumbler. Go fish, kite or surf for a bit. Come back to your beer just as cold as when you poured it.
Since this is a vacuumed sealed tumbler the outside of the tumbler will still be air temperature. That means no sweat down your glass. Not leaving a trail of water rings on every counter or table top you put your drink down on is a huge plus.
There is no test like the hot car test. Fill the Yeti Tumbler with ice water in the morning. Leave it in your truck while you are at work all day and come back to ice water in the evening.
If you wash the Yeti Tumblers in the dishwasher there is a good chance that they will be ruined. The extreme hot or cold can pop the seal on the double insulated construction and air can sneak in to replace the vacuum.
The cap is machine washable and the rubber gasket can be removed for a deep cleaning. This lid is not spill proof. So if you dump over your coffee, you will get some in your lap. The rubber gasket keeps the lid on even in bad wipe outs but you will loose some of your drink through the drinking hole.
Yeti makes a killer Straw Lid. If you drink shakes or smoothies, get one of these.
Why You Want the Yeti Rambler Tumbler:
We could not figure out what the obsession was with these things before we owned them. Once we had one, we bought more and now don't leave home with out them. None of the other glasses in my house get used anymore. Water, beer, juice, coffee, cocktails and tea are always better cold or hot. With the Yeti Tumblers, your drinks are always the temperatures you want them.
Having only one Yeti Rambler Tumbler is not enough. Once you use this tumbler, you will become so attached that you have to buy more.
