This shade sail is very high quality and is the perfect size over our pool. We originally had a 16’ and it was too small that it would barely cover half the pool. The bottom of our pool is dark pebble and heats easily, but with this sail over the water it stays nice and cold in the triple digit heat. The sail was easy to install, sturdy, a great size, and there is cable that runs through all three sides that keeps it in good shape. Highly recommend if you need a nice shade sail.
