Its 16-mil thickness and thermal bubble design are effective in trapping heat from the sun, which can warm up the pool during sunny days and maintain the temperature during cooler nights. The polyethylene material promises durability and longevity, even under harsh weather conditions, while also being lightweight and easy to install or remove.

The blue color of the cover not only looks appealing but also contributes to UV protection, which is crucial for minimizing water evaporation – claimed to be reduced by up to 95%, helping conserve water significantly. Additionally, the cover can be trimmed to fit pools of various shapes, making it versatile for both in-ground and above-ground pools.

However, at 50.9 pounds, it might be a bit heavy for some users to handle. Given its size of 16 x 32 feet, it is suitable for larger pools.
