Why choose sun protection clothing (II)

How is UPF different from SPF?

UPF measures the amount of UV radiation that can penetrate fabric and reach your skin. The sun protection factor, or SPF, is based on the time it takes for UV-exposed skin to turn red; if you burn after 20 minutes, if used correctly, SPF 15 sunscreen can protect your skin 15 times longer.

Another important distinction: UPF measures both UVB and UVA rays, while SPF only measures UVB.

What makes clothes sun resistant?

Yes, your clothes protect you from the sun, but not all fabrics and colors provide the same protection. Fortunately, you have plenty of options. When shopping for sun protection clothing that can effectively protect you from harmful rays, keep these factors in mind:

Color: Dark or bright colors block UV rays from reaching your skin by absorbing them rather than allowing them to penetrate. This is why these colors offer better protection than lighter shades.

Construction and Civil Engineering: Densely woven fabrics, such as denim, canvas, wool or synthetic fibers, are more protective than sheer, thin or loosely woven fabrics. Check the sun protection clothing of a fabric by holding it up to the light. If you can see through it, UV rays can easily penetrate the fabric and reach your skin.

Content: The composition of your fabric really matters. Unbleached cotton contains natural lignins which act as UV absorbers. Shiny polyesters and even lightweight satin silks can be very protective because they reflect radiation. High-tech fabrics treated with chemical UV absorbers or dyes prevent some penetration of UV rays.

Fit: Loose clothing is best. Tight clothing can stretch and reduce the level of protection offered, as the fibers move away from each other and allow more UV light to pass through.

UPF: Some clothing manufacturers provide UPF labels, which indicate exactly how much of the sun's rays the clothing can protect. Look for our Seal of Recommendation every time you shop.

Coverage: The more skin your outfit covers, the better your sun protection clothing. Whenever possible, choose long-sleeved shirts and long pants or skirts.

Activities: Regardless of UPF, if your clothes are stretched or wet, they will lose some of their protective ability and become more transparent, exposing your skin to more UV light.
