Thoughtfully engineered with all of the qualities of glass- but lightweight, durable and sustainable. The Kor Nava Water bottle includes a built-in straw with a filter that is made of 100% pure coconut shell. This durable, dent proof vessel is also BPA free, leak proof and one-click technology makes sure you never lose your cap. The no-slip base provides a soft landing so your bottle stays put. The Audi Sport logo is printed on one side.
