Consumer alert from May 2001 on choosing clothing that protects against ultraviolet rays
More than 1 million people would be diagnosed with skin cancer in the United States in the year this alert was issued, according to the American Academy of Dermatology figures it cites. Sunscreen and limited sun exposure reduce that risk, and so does clothing chosen for protection. The Federal Trade Commission, which monitors advertising claims in this area, explains how sun-protective fabrics differ from typical summer fabrics and what the labeling on sun protection products means, so shoppers can choose carefully before heading to the beach, the tennis court or the park.

Sun-Protective Clothing - Wear It Well - Alert from May 2001 Regarding UV Protection
Research Directory Education Fashion Industry
It's important to understand the labeling information on sun protection products and shop carefully before heading to the beach, tennis court or park. The Federal Trade Commission carefully monitors advertising claims in this area and offers this information to help you make wise purchasing decisions.
Sun-protective fabrics differ from typical summer fabrics in several ways. Sun-protective fabrics typically have a tighter weave or knit and usually are darker in color. Garments made with these fabrics may have a label listing the garment's Ultraviolet Protection Factor (UPF) value, that is, the level of protection the garment provides from the sun's harmful ultraviolet (UV) rays. The higher the UPF, the higher the UV protection.
The UPF rating indicates how much of the sun's UV radiation is absorbed by the fabric. For example, a fabric with a UPF rating of 20 allows 1/20th of the sun's UV radiation to pass through it. This means that the fabric would reduce your skin's UV radiation exposure by 20 times where it's protected by the fabric.
There are three categories of UPF protection:
Garments with a rating above UPF 50 may be labeled UPF 50+; however, they may not offer substantially more protection than those with a UPF of 50. Also, a garment shouldn't be labeled "sun-protective" or "UV-protective" if its UPF is less than 15. In addition, sun-protective clothing may lose its effectiveness if it's too tight or stretched out, damp or wet, and worn and washed repeatedly.
You may see labels on sun-protective garments stating that the garment meets standards developed by the American Society for Testing and Materials (ASTM). ASTM is just one organization that has developed a standard guide for the testing and labeling of UV protective fabrics. While manufacturers don't have to comply with the ASTM standard guide, those that say they do must label their garments with UPF values.
Here are some other ways to make working and playing outdoors sun-safe.
The above educational alert regarding UV Protective Clothing is from the FTC. The article has been obtained by the Apparel Search Company on September 4, 2007 from https://www.ftc.gov The alert had originally been posted on the FTC website May 2001.
The FTC works for the consumer to prevent fraudulent, deceptive and unfair business practices in the marketplace and to provide information to help consumers spot, stop, and avoid them. To file a complaint or to get free information on consumer issues, visit www.ftc.gov or call toll-free, 1-877-FTC-HELP (1-877-382-4357); TTY: 1-866-653-4261. The FTC enters Internet, telemarketing, identity theft, and other fraud-related complaints into Consumer Sentinel, a secure online database available to hundreds of civil and criminal law enforcement agencies in the U.S. and abroad.

Construction and color do most of the work. Sun-protective fabrics typically have a tighter weave or knit than ordinary summer fabrics, leaving fewer gaps for ultraviolet rays to pass through, and they are usually darker in color, which absorbs more UV before it reaches the skin. Garments made from these fabrics may carry a label listing an Ultraviolet Protection Factor (UPF) value — the level of protection the garment provides from the sun's harmful ultraviolet rays — which lets a shopper compare garments the way SPF values compare sunscreens.
The alert is also a lesson in reading claims. Because the FTC carefully monitors advertising in this area, phrases on hangtags and in advertisements for sun protection products are held to substantiation standards, and the guidance walks consumers through the labeling information before they buy. The retailer, factory, swimwear and wholesaler directories linked at the end of the page show the trade side of the same subject: by 2001 sun protection had become a defined product category with its own suppliers, including UV protection chemicals for fabrics and children's UV protective swimwear.
They typically have a tighter weave or knit and usually are darker in color, and garments made with them may carry a label listing the garment's Ultraviolet Protection Factor (UPF) value.
The level of protection the garment provides from the sun's harmful ultraviolet (UV) rays, so protection can be compared from garment to garment before buying.
