Your pint or tumbler is your constant companion, whether on the way to work, at a picnic in the park, at a festival, or in the stadium; the cool stainless steel cup always has to come along and becomes the vessel for your favorite drinks, from coffee, beer, and soda to water or iced coffee. What’s special about this lid: the drinking opening can be easily opened and closed, and a straw can be inserted into the center – of course, a stainless steel straw from Klean Kanteen. Because you aren’t always sitting still when you drink, but instead walk around, chat with people, or throw your arms up when your team scores a goal, this lid is the perfect companion for your pint and tumbler. Exception: The lid does not fit the 295 ml (10 oz) pints. Please also note that the lid is not leak-proof, but only splash-proof.
