It has a double-wall, vacuum-insulated construction, and keeps your water cold (or coffee hot) until the last sip. A variety of colors are available, and custom colors are available. This cup is available in two types of lids, a special Chug Cap and a folding straw lid. The special Chug Cap has a special smallmouth outlet, which can help you avoid the embarrassment caused by drinking too much water. Get to drinking faster with the Chug Cap. It just takes a quick half-twist of the handle to open and then you're good to go, making it easy to steal a sip without slowing down.
