O.5.4.5.2 Clothing made from a material with a close weave should be chosen as it is more protective against UVA and UVB than clothing made from loosely-woven materials. Shiny, dark materials provide more protection than light-coloured pastel shades or materials with a rough finish. Dark colours usually absorb more UV rays than lighter colours but have the disadvantage of absorbing heat as well. Bright colours, e.g. reds and yellows, give more protection than pale ones. White fabrics containing optical brightening agents (often found in washing powders and liquids) absorb both UVA and UVB rays, but especially UVA. Choose clothing that covers as much skin as possible.O.5.4.5.3 Clothing with built-in protection against UVB is made by several manufacturers and is recommended. There is a rating system for such sun-protective textiles and clothing, known as Ultraviolet Protection Factor (UPF), which represents the ratio of UVB protection when measured with and without the protection of the fabric.
