Imagine a warm day out in the sun and your water bottle's plastic skin is slowly bringing your once cool water to a slow boil. As you put your lips to the water bottle, the warm water drips out and starts to burn your lips like lava rolling over dry brush. The Polar Insulated Water Bottle combines the thermal properties of an insulated vacuum bottle with the lightweight advantages of a standard plastic bottle. Fill your bottle with liquid and ice and enjoy cool water till your last drop. For even hotter days, fill your Polar Insulated Water Bottle and freezer before your ride or run. No matter how you prepare, your Polar Insulated Water Bottle will keep you water cold twice as long as conventional bottles. The 12 ounce size is ideal for runners and kids and the standard size will fit into any water bottle cage. Polar's wide mouth design makes it easy to fill with ice and for cleaning. Once filled with liquid, the dual-wall construction and insulateing layer of air keeps heat out and cool in.
