UPF
Fabric sun protection
UPF stands for ultraviolet protection factor, a rating system for sun-protective clothing and fabrics.
Like SPF for sunscreen, higher UPF numbers indicate greater protection from ultraviolet radiation.
A UPF 50 shirt blocks about 98% of UV rays: I wear UPF clothing when I'm out on the water all day.
