Product description: Double wall, 16 oz stainless steel Sipper Straw Bottle with flexible straw. 

What we like about this mug: Miir has become the leader in manufacturing technically superior drinkware products in a way that is both ecologically conscious and committed to finding ways to give back. 

With Miir's practices as a foundation, we love having the opportunity to offer a custom designed 16oz Sipper Straw Bottle made from stainless steel to keep drinks cold for hours and features a flexible straw for easy one-handed sipping.
