Insulated Leak Proof Straw Lid: Built for easy drinking on the go, the lid is leak proof when the nozzle is in the closed position and has extra insulation to keep your beverage colder longer. Includes two straws.
US Patent Pending Design: The straw nozzle extends past the edge of the lid for a better drinking experience. 
Not Intended for Hot Liquids: Pressure may build within the bottle causing leaks or spills.
