Arctic Armor winter pool covers provide essential off season protection by shielding above ground and inground pools from harsh weather and heavy debris. Available in solid and mesh varieties, these highly durable covers prevent algae growth by blocking sunlight and keep freezing water out of your pool structure. This ensures a much faster and cleaner spring opening. For a complete and secure winterization process, pair your solid cover with a reliable cover pump to prevent water accumulation. Additionally, using an air pillow beneath the cover helps absorb ice expansion and protects your pool walls from winter damage.
