Sun protection: What does UPF50+ mean?
UPF indicates the degree of protection from the sun (Ultra Violet Protection Factor). It is a world-recognised standard.
It indicates the level of protection provided by the fabric, and more precisely the amount of UV absorbed.
To comply with the standard, it must prevent absorption of at least 95% of UV rays. UPF 50+ means that the fabric prevents the absorption of at least 95% of UVA and 98% of UVB.
