Sunlight is important for human health. For example, the body needs sunlight to form vitamin D, which is important for bone structure, but at the same time, the ultraviolet rays contained in sunlight pose major potential stresses and risks to the skin. The number of skin cancer cases recorded by dermatologists around the world has increased significantly due to changes in the way people spend their leisure time. According to the latest estimates, experts expect more than 200,000 new skin cancer cases per year in Germany alone. Dermatologists are therefore warning against excessive exposure to the sun and calling for preventive measures such as suitable clothing and sun-protective textiles. This is particularly important for children, whose skin is extremely delicate and who do not develop full protection against harmful UV radiation until they are around 15 years old. UPANDFAST's specialized sun-protective fabrics.

Using suitable materials and construction, UPANDFAST's specialized sun protection fabrics determine the UV Protection Factor (UPF) according to the measurement methods and expert tests provided by the International Test Association for Applied Protection against UV Radiation. Children's swimsuits offer particularly good protection against solar radiation, achieving a UV Protection Factor (UPF) much higher than that of the strongest sunscreens (sun block creams).
