Combining the thermal properties of an insulated vacuum bottle with the lightweight, flexible features of a plastic bottle, the Polar Bottle Sport insulated water bottle is the ideal choice for cyclists. With three insulating layers, the Polar Bottle Sport will keep liquids cold more than twice as long as conventional water bottles. It's free of BPA and phthalate so it's safe and won't make your water taste like plastic. Even when left outside, the inner foil liner reflects solar rays so a hot sun won't cook your beverage before you can enjoy it. The wide mouth easily fits ice cubes and the removable drinking valve makes thorough cleaning a breeze. There's no need to save this bottle for biking -- the 12 ounce size is small enough that you can throw it in a purse, lunch box or even carry with you on a walk or run.
