narrow mouth non-insulated 40oz, black shale
the classic klean kanteen single-wall water bottle, lightweight and designed to last and last... and last! the bottle itself is made from 18/8 food grade stainless steel, and the lids are BPA free. an electropolished interior means that the bottles won't retain flavor from beverages. ready for any adventure - school, work, road trips, hiking, you name it!
care & cleaning: we recommend handwashing painted and all vacuum insulated bottles, vacuum insulated tumblers and vacuum-insulated canisters.
for thorough cleaning, you can use warm, soapy water and a bottle brush. baking soda is also recommended.
if your bottle or cap seems to be retaining flavors or smells, use diluted vinegar and soak them in it overnight. NOTE: the Stainless Unibody Bamboo Cap should not be soaked or immersed.
