This Comfortpool Solar Cover has two properties. First, it protects against dirt, keeping the water much cleaner. The second property is that it heats the water. As the sun shines on the cover, the water heats up. At the same time, the Solar Cover, thanks to its special bubble wrap, provides insulation. The cover retains heat, preventing the water from cooling down, for example, at night. This allows you to enjoy wonderfully warm water for a long time. This Solar Cover is suitable for pools measuring 282 x 196 cm.
