Evaluation of Ultraviolet Protection Claims Made by Umbrella Brands

The marketing of umbrellas for use in the sun as a shade structure favors the use of UPF claims despite the absence of a standardized definition. The lack of validation for these claims along with inherent limitations of UV protection offered by shade structures suggests the UPF claim may be more of a promotional tactic than a reliable indicator of the UV protection provided. This underscores the need to continue recommending other sun-protective behaviors, such as wearing sunscreen and sun-protective clothing, even while using umbrellas.
