Our swimwear fabric is designed to protect your skin from harmful UV rays, with a UPF rating of 50+. UPF stands for Ultraviolet Protection Factor, which measures how much UV radiation can penetrate the fabric and reach your skin. A UPF rating of 50+ means that only 1/50th (or less than 2%) of the UV rays can pass through the fabric, which is the highest level of protection available. Our swimwear fabric can help you avoid sunburns, skin damage, and skin cancer, while enjoying the outdoors.
