All Gordon Wear products are UPF 50+ -- we take no chances with sun damage.
* Actually, our hats have tested between UPF 300+ and UPF 1000+ which exceeds all international recommendations and means that they block 99.999% of UV-A and UV-B radiation.
What is UPF?
UPF is the gold standard for measuring sun protective fabrics. A UPF rating indicates the transmittance of UV radiation (measured using a spectroradiometer and an artificial light source) and translates this result based on the sunburn action spectrum (erythema action spectrum).
What about SPF?
SPF is a rating used for suncream and other lotions. It measures the how well a liquid is absorbed into the skin is not applicable for fabric. A hat with an "SPF" rating is not guaranteed to protect you from harmful skin damage.
