Californian brand, born with the mission of reducing the single use of packaging. High-quality stainless-steel product (almost handmade) and BPA free. Multiple uses and great thermal capacity. The main material used in all its bottles is stainless steel, due to its safety, durability, its non-reaction with other chemicals and its capacity to keep unique flavors. All Klean Kanteen products (bottles, glasses, jars …) are very sustainable over time and maintain their qualities.
