The waterproof pool cover can extend the life of the pool and make it more durable. NOTE: (Excluding the pool) The pool cover is made of high-quality anti-UV woven fabric and is durable. These pool covers fit snugly over the pool to prevent leaves, dust, and debris from accumulating in the pool. The wear-resistant rope is fixed to prevent it from being blown away by the wind. Limit evaporation and reduce the need for chemicals. Please note that due to manual measurements and display differences, there may be slight differences between individual products and images.
