The Contigo Evoke Water Bottle is designed with an attached lid and a quick-twist mechanism that allows for easy access, so there’s no need to unscrew the lid fully to drink. A quick, quarter twist opens the lid, which also stays open so you can drink with one hand. The large spout makes it easy to sip water and fits full ice cubes. It seals fully with a simple snap-to-close, so you can throw it in a bag without worry. For added security, there is a sliding lock that prevents the lid from being opened. The bottle also comes in multiple high fashion colors and includes a smooth, silicone carry tether. For cleaning hard to reach areas, simply unscrew the entire lid from the bottle and wash with easy access. Keeps beverages cold for 15 hrs.
