Klean Kanteen's quest to find and replace single use items knows no bounds. These tumblers lead the charge replacing years of single use cups while handily outperforming plastic and paper. The best way to replace a single use item is not just to make a durable replacement, but one that can do more. Anything a single use paper or plastic cup can do, our stainless steel vacuum tumbler can do much better. Iced tea, IPA or Caramel Latte Vacuum insulation and electropolished stainless steel combine to protect the taste and temperature of whatever you put inside. A quick rinse or wash will take you from your morning pick me up to staying hydrated at work to a fresh smoothie at the gym.
