Doheny's Clear-Tek Micro Bubble Solar Pool Cover for Above Ground Swimming Pools | Increase Solar Energy Absorption, Retain Heat, Reduce Evaporation, Reduce Heat Loss & Save, 21 ft Round Clear 3200

Extend your swim season with a Doheny’s Solar Pool Cover designed specifically for above ground swimming pools. Constructed from UV-stabilized polyethylene with a durable thermal bubble design, this solar blanket captures the sun’s energy during the day and helps retain warmth overnight for more consistent water temperatures. The insulating air bubble construction floats directly on the surface of the water, helping reduce evaporation and minimize heat loss while supporting more efficient chemical usage. Designed for seasonal durability, the material resists sun exposure and normal pool conditions without becoming brittle or losing flexibility. Available in multiple thickness options and compatible with standard round and oval above ground pool sizes, this solar pool cover can be trimmed for a more precise fit. Ideal for pool owners looking to improve heat retention and extend comfortable swim time without additional heating systems.
