UPF-Ultraviolet Protection Factor- Rating

                                                                                        

UPF (Ultraviolet Protection Factor)  is a rating system used for garments,  hats included. It shows how effectively your clothing is protecting you from ultraviolet A and B rays.

 UPF RATING PROTECTION RATING % OF UV RADIATION BLOCKED
15-20 Good 93.3-95.9%
25-40 Very Good 96-97.4%
50, 50+ Excellent 97.5% or more

 

In general better protection is provided by:

  • Dense fabrics (tightly knit/weaved)
  • Thicker fabrics
  • Darker colors generally provide better protection due to higher concentration of dyes that disrupt UV rays. The color in itself does not provide any protection.
  • Laundry additives, such as optical brightening agent (OBA)  in detergent can boost UV protection.
  • Polyester and nylon disrupt UV rays well: Wool and silk. Moderately: Natural fibers, such as cotton, rate low, unless otherwise treated
  • Wet, faded and stretched fabric could lose it's UPF rating by upto 50%

For garments to be labeled as "sun-protective" a minimum of UPF15 rating is required.
