Chill out with our Insulated Polar Bottle! Chilled water stays cool 2X longer in this double-walled bottle than it does in a single-walled bottle! The reflective foil layer between the double walls reflects the sun's rays for added insulation. For best results, partially fill the bottle with water then freeze overnight. Add more water when you're ready to go and your water stays cooler, longer! The drinking valve can be removed from the cap for deep cleaning.
