Klean Kanteen

At Up and Under in Cardiff, we stock a range of Klean Kanteen products, known for their commitment to sustainability and innovative design. Klean Kanteen was founded in 2004 by inventor Robert Seals, who crafted the first reusable stainless steel water bottle in the U.S., free from aluminum and BPA liners. His groundbreaking design offered a safer, more sustainable alternative to single-use plastics at a time when their environmental impact was just becoming evident.
What began as a small operation at music festivals and environmental fairs quickly grew into a global movement. Under the leadership of the Cresswell family, who took over in 2005, Klean Kanteen has championed the Bring Your Own™ revolution, creating durable, versatile, and eco-friendly products that inspire change and reduce single-use waste.
