Original 18/8 stainless bottle designed to be the healthy alternative to polycarbonate and lined-aluminum reusable bottles. From the onset; free of BPA, Phthalates, lead or other toxins. Today, our Classic line continues to be revered by many for its iconic place in history and for it's durability and prolonged performance. Made from high quality, 18/8 food-grade stainless steel, the Classic is safe and toxin-free, and doesn't retain or impart flavors. No matter how many times it is filled, or what is put into it, these Kanteens keep drinks fresh and clean tasting. With a variety of cap and color options, tailoring a Classic to your lifestyle is effortless. The 1.75" mouth opening is easy to drink from and is large enough for ice cubes and bottle brushes (for thorough cleaning).
