The TKWide 32oz uses Climate Lock double-wall vacuum insulation to keep drinks hot for 24 hours or cold for 50 hours, performance that matches or exceeds competitors at any price point. The 18/8 food-grade stainless steel interior is electropolished to resist flavor retention and staining, meaning the bottle transitions from morning coffee to afternoon water without taste contamination.
The wide 54mm mouth accommodates ice cubes and cleaning brushes, and the internal thread design eliminates the external threads that collect grime on competing bottles. Klean Kanteen's interchangeable cap system allows owners to swap between the Chug Cap, Straw Lid, and Cafe Cap depending on use, and all replacement caps are sold individually.
The company is a Certified B Corporation and 1% for the Planet member, and their Strong-as-Steel warranty covers manufacturing defects for the life of the product. At $35-$40, the TKWide costs less than two months of daily disposable coffee cups while lasting a decade or more.
Klean Kanteen builds the bottle that made single-use containers look obsolete.
