Let's thank the folks at KLEAN KANTEEN for developing the best stainless steel water bottle on the market! Here is a safe alternative to plastic and lined metal containers that is made from high quality food grade stainless steel. This non-leaching and toxin-free stainless steel has NO inner lining and is so clean tasting. While the wide mouth fits ice cubes, the slim 27 oz. design fits most cup/bottle holders. These bottles are durable, lightweight reusable and 100% recyclable!! Please note that the colored bottles come with the loop caps only.... however you can purchase the sports cap seperately and affordably! - Jill :)
