This is a rating given to clothing to indicate how effectively the fabric blocks ultraviolet radiation (Ultraviolet Protection Factor). A UPF rating of 25 means that only 1/25th (or 4%) of the UV radiation can penetrate the fabric. The lower the rating, the least protective it is protective. To be effective, a garment should hold the UPF50+ rating in order to filter 98% of harmful UV rays.
