UV Cut is affected by fabric color, weave/knit, and material. We base our testing standards on white fabric, generally the least effective. Even our light-colored fabrics block more than 90%of UV radiation, offering a way to reduce exposure. Use sunscreen and other methods to further increase protection. (Exceptions may apply to mesh fabrics.) UV Cut is NOT the same as UPF, which measures how much UVA / UVB a fabric allows to reach your skin. These are NOT equivalent ratings and use different testing methods....
