The major concern for those out in the Sun is how their skin will be affected. With Pyramid Shades, you don't need to worry about that. Due to its closed design, the shade protects you from 3 sides.
Fabric is ARPANSA certified. The Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) is the Australian Government's primary authority on radiation protection and nuclear safety.
Studies have shown the actual sun protection factor of an umbrella “is probably between (SPF) 3 and 7 in real-life” (assuming the fabric blocks out all harmful rays). This is why coverage from the sides is very important!
One Pyramid Shade utilises the fabric equivalent to approximately two and a half umbrellas.
