UPF 40+ (UPF) measures the amount of UV radiation that penetrates a fabric and reaches your skin. A fabric rated with a UPF of 40 will allow only 1/40th of the sun's UV rays to pass through. Samples of fabrics have been tested for UV protection at Bureau Veritas Consumer Product Services in accordance with the standard AATCC 183:200 "Ultraviolet Protection Properties for Fabric."
