The Pure Bottle lets you enjoy the simple taste of clean, cool water. The bottle is constructed of odorless and tasteless, BPA-free Tritan - drinking on the go has never been more appealing. The Flip Straw allows you access to fluids without unscrewing the cap or tilting the bottle. The 1 liter size is perfect for maintaining proper hydration levels by sipping all day, while the 700 ml and 500 ml fit in bike cages and car cup holders for refreshment on the move. The wide-mouth, screw-top lid is easy to grip and large enough for easy filling and cleaning. And a functionally attractive shape and variety of colors make using our bottle a pure joy.
