Polar Designs Insulated 24oz Water Bottle

Combining the thermal properties of an insulated vacuum bottle with the lightweight, flexible features of a plastic bottle, the Polar Bottle® is the ideal choice for active people. Simply fill with liquid and ice and hit the trail. For even longer cooling power, fill your Polar Bottle® and store it in the freezer before use. Either way, it will keep liquids cold twice as long as conventional water bottles.
