Pool cover

A woven pool cover fabric comprising:

• a repeating geometric pattern with a plurality of first lines in a warp direction and a plurality of second lines in a fill direction that cross one another to form a plurality of repeating geometric shapes, the plurality of geometric shapes being a first geometric shape and a second geometric shape that alternate across each of the first lines and second lines;
• a water flow rate of about 10 gallons/minute per square foot to about 200 gallons/minute per square foot as measured by ASTM D4491 test;
• a shade coverage of about 80% to about 99%;
• and
• wherein the first geometric shape has a weave pattern that is different from a weave pattern of the second geometric shape;
• and
• wherein the first geometric shape in a first line of the plurality of first lines is offset with respect the first geometric shape in a second line of the plurality of first lines that is successive with the first line of the plurality of first lines;
• and
• the second geometric shape in the first line of the plurality of first lines is offset with respect the second geometric shape in the second line of the plurality of first lines that is successive with the first line of the plurality of first lines.
