UPF - Ultraviolet
Protection Factor
-
You may have
heard about the SPF (Sun Protection Factor) used by sun
tan lotions to measure the protection the lotion offers
to your skin but you may not be aware that there is a parallel
standard for clothing - the Ultraviolet Protection Factor
or UPF rating system.
The UPF rating
is a measure of a garment's protective ability, based on
how much UV (Ultraviolet) rays can get through a fabric
to the skin. The ultra violet protection factors go much
higher than sun creams. The higher the UPF score, the higher
the protection. The highest rated garments offer Factor
50+ protection which means less than 1/50 th (or less than
2% penetration) of the UV rays reaches the skin.
