What does a rating of UPF 50+ mean?
The fabric used in many of our hats has a rating of UPF 50+. This simply means that this fabric only allows 1/50th of the UV radiation falling on the surface of the hat to penetrate. The high-density fabrics have been independently tested by a third party company assuring you of a tighter woven premium hat that protects your skin against the harmful UV rays. Wearing UPF 50+ (not SPF) rated hats are a smart healthy habit for protection from harmful UV sun rays.
