Fisher Textiles offers several fabrics for outdoor apparel applications that have been tested for Ultraviolet Protection Factor (UPF) under AATCC 183 with values ranging from 15-50+. UPF is a rating generally used for clothing and other fabrics that protect skin from the sun. It measures the amount of UVA and UVB radiation that penetrates the fabric and reaches the skin. These fabrics are excellent for swimwear, outdoor athletic jerseys, and vanity face masks.
