Contigo is a brand of thermos that are sleek, useful, and durable. They have a great casing that allows you to grip the container (for both left and right handed individuals!) even when the liquids are hot or cold. The snapseal is a well-designed mechanism that allows you to open and close the bottom with ease but still leakproof. Because the stopper is rubber, it better insulates the temperature of your drink. The temperature of your drink can be sustained for long periods of time. The thermos is also designed to be easily cleanable – including the snapseal mechanism!
