Kookaburra Waterproof Garden Sun Shade Sail Canopy in Polar White - 98% UV Block Kookaburra Shade Sails - Protects you from the sun all day long Woven shade sails are the most effective sail shades for offering maximum UV protection. The ultra-tight weave of the fabric has been independently tested to UPF50+ making these sail shades near impenetrable by sunlight. More than 98% of harmful UV rays are blocked out as a result. In warmer climates, sail shades are designed with small holes in the weave to allow hot air to escape and to keep it from getting too warm underneath the sail. However, with the British climate generally cooler than many countries and more prone to showers, a tighter weave is ideal. You can enjoy maximum UV protection and shelter from the rain without worrying about being uncomfortably warm beneath your sail shade.
