Our Taffeta reinforced covers resist wearing and provide superior strength which other non-reinforced covers cannot duplicate. These solid covers are meant to keep rain and melting snow out, leaving properly treated water clean and clear until spring. Remember these covers are solid, standing water must be pumped off the top to prevent drowning risks to children or pets that might stray onto the pool cover. Hydra also offers this cover with a mesh drain for those who love the advantages of a reinforced cover but don’t want to pump off the puddled water.
