Even through a thick layer of cloud, 90 percent of UV rays penetrate. Textiles hinder a lot but the differences are big.
Protect these items
The classic white cotton T-shirt still allows 40 percent of the radiation to pass through. A wet shirt passes two to four times more UV radiation than a dry one. Lightly woven fabrics – linen, summer cashmere, loosely woven shawls – do not protect as well as chemical fibers (polyester, nylon). This is because synthetic fibers can be processed more closely than natural fibers. Silk is recommended if it will be a natural fiber.
The same goes for hats. Airy straw hats offer less protection than tight-knit ones. If you turn the hat inside out and too much light gets through, it’s not ideal sun protection.
Blue protects best
When it comes to light clothing, the darker the better. But the best protection is indigo, not black. Color doesn’t play an important role in thick clothing: a white winter sweater is virtually UV-proof.
Special sun protective clothing
There is a good range of sun protection clothing available today, some of which contain additional chemical filters. The layman can only understand how good the garment is with the seal of approval.
The “UV Standard 801” seal is considered the strictest. Here the sun protection does not decrease even after frequent washing. A UPF (Ultraviolet Protection Factor) of 50+ means that a fabric allows less than one-fifth of UV radiation.
