Why customers choose PatioZora Garden

Extend the swimming season with reliability

The Sapphire Series Round Solar Pool Cover by Yankee Pool Pillow captures solar warmth and passes it to your water, helping you enjoy comfortable swims longer into the season. Its robust build is designed for outdoor use and everyday family life.

Why this cover stands out

  • Durable Duraflex 16-mil polymer resists UV exposure, so it stays strong against sun and weather.
  • Air-bubble pockets trap heat and help keep water warmer, even on cooler days.
  • Reduces water loss by evaporation by up to 95%, helping maintain water balance and chemical use.
  • Helps keep leaves and dirt out, reducing debris and cleaning time.

How it works in everyday use

As sunlight shines on the cover, heat is captured in the air pockets and gently released into the pool water. On breezy mornings, the blanket can still contribute warmth and keep the surface calmer.

Real-life scenarios

  • End-of-season extension: a warm pool surface invites you to dip in sooner during shoulder seasons.
  • Cloudy or partly sunny days: the heat-trapping pockets may deliver noticeable warmth for casual swims.
  • Busy weekends: with debris kept out, you spend less time skimming and more time enjoying.

Specifications and care

Designed for 21 ft round above-ground pools. The 16-mil polymer is tough, UV-resistant, and weatherproof for outdoor use. When not in use, rinse, dry, and store flat to prevent creasing.
