UPF stands for Ultraviolet Protection Factor and indicates how much of the sun’s UV radiation is absorbed. A fabric with a rating of 50 will allow only 1/50th of the sun’s UV rays to pass through. This means the fabric will reduce your skin’s UV radiation exposure significantly. All of our UPF finishes last the life of the garment, an industry standard of 30 washings.
