I used to have a shade sail when growing up back in Australia and they really do provide a significant reduction in both rays and temperature underneath. They can turn an area that’s unbearable on sunny days into a really pleasant place to escape the Summer heat and are ideal for use over pools to stop you getting burnt when splashing about.
This Square Sail Sun Shade offers a 90-percent UV reduction (for tanning you’ll need to recline under one of the unshaded arcs) and includes a whole kit of installation hardware to get it sailing. Tip: Make sure to secure each point to something strong as the wind can really grab hold of it. Measuring 11 foot 10 inches square and available in a range of colors, the Square Sail Sun Shade is a popular item over at Overstock.com, where it can be picked up for a bargain $89.99 (compare at $268.00).
