What Does UPF Stand For?
UPF stands for UV Protection Factor
UPF, or UV Protection Factor, is a rating system that measures the effectiveness of fabrics in blocking ultraviolet (UV) radiation from the sun. The higher the UPF value, the greater the protection offered against harmful UV rays, helping to reduce the risk of skin damage and sun-related health issues. UPF-rated clothing is essential for outdoor activities and provides a proactive approach to skin safety in sun exposure.
