Ultraviolet Protection Factor (UPF)

Ultraviolet Protection Factor (UPF) measures how well clothing and fabrics protect your skin from ultraviolet (UV) radiation, which can cause sunburn and skin cancer. The UPF rating indicates the amount of UV radiation that can pass through the fabric. For example, a UPF of 30 means that only 1/30th of the UV rays can penetrate the fabric, offering good protection. Higher UPF ratings provide greater protection, so clothing with ratings of 50 or more is considered excellent. Wearing UPF-rated clothing is an effective way to reduce sun exposure while enjoying outdoor activities.
