It is a global standard for UV protection established in Australia/New Zealand, quantifying how much UV radiation a product can block. The UPF value is based on the amount of time it takes for skin to redden from UV exposure, assuming about 20 minutes of unprotected exposure. UPF30 means that the product will protect you from sunburn for 30 times longer. UPF15 or higher is considered "good," products with UPF30 are considered "excellent," and UPF50+ (plus) is considered "very excellent," protecting against the effects of UV rays.
