The Klean Kanteen Insulated TKWide is a stainless steel bottle that is perfect for coffee, tea, water, smoothies and other types of hot and cold drinks. You can take the bottle with you wherever you go, so it is perfect for daily use, hikes or while exercising. The caps of the TK Wide collection have been improved. They now feature the TK Closure design with an internal screw thread to make sure the thermos function works even better. Warm beverages stay warm for up to 14 hours and cold drinks stay cold for up to 47 hours. The cap also has a rotating loop, making the bottle easy to carry.
