We all know that when we are running in the sun we are supposed to be wearing sunscreen with an SPF factor, but fighting the rays just got easier with workout clothes with UPF!
What Is UPF?
An Ultraviolet Protection Factor (UPF) seal means the fabric blocks UVA and UVB rays. To earn a UPF label, clothing must undergo tests for both initial UV protection (determined in part by the tightness of the weave, the weight, the type of fiber, the color, and the amount of skin covered) and protection after two years of use. Most high-tech performance wear is specially treated with chemical UV absorbers, which partially block UVA and UVB rays. In addition, some fabric are treated with a chemical sunblock.
From Lands' End, this short sleeve shirt ($29) has a UPF 50+.
So before you take that run in the sun, slather on the sunscreen and sport apparel that fights both UVA and UVB rays.
