Meet the makers

After dipping our toe into the world of ice baths we quickly realized there was no solution to safely securing our stock tank from pollen, insects, leaves and other debris outdoors. As a husband and wife entrepreneur team, we set out to create the best stock tank cover for other cold therapy lovers. We worked hard to create each cover with care, selecting the best materials and sending each package from our own mailbox. We hope your Polar Protector will make your life easier and your water colder! Happy plunging and thank you for supporting our dream!
