UV Protection Shirts: What They Do and What Families Should Look For

Paris – 18 July 2026: UV protection shirts are increasingly becoming standard equipment for many families during the summer. They are intended to protect children and adults from harmful solar radiation during days at the beach, swimming or sports, while reducing the need to repeatedly apply sunscreen to large areas of skin. However, experts stress that such a shirt is an additional protective measure, not a free pass to spend longer periods in direct sunlight.

The protective effect depends primarily on the fabric. Densely woven or specially treated materials block ultraviolet radiation more effectively than very thin, loosely woven textiles. Consumers should look for clear UV protection labelling. The French standard NF EN 13758-2+A1 sets out requirements for the classification and labelling of clothing intended to protect against solar UV radiation.

A high UV protection factor is particularly useful for extended periods outdoors. At the same time, the garment must actually cover the body: a short-sleeved shirt protects neither the forearms, hands, face nor neck. For children, a combination of a long-sleeved top, a wide-brimmed hat and suitable sunglasses is therefore recommended. Exposed areas of skin must still be carefully protected.

Sunscreen remains necessary on uncovered skin. The National Cancer Institute points out that clothing, shade and avoiding the strongest midday sun are the most important measures. Sunscreen complements these precautions but does not replace them. It should be reapplied regularly during summer activities, especially after swimming, heavy sweating or drying off with a towel.

Caution is also needed when swimming. Water does not reliably protect against UV radiation, while light can additionally be reflected from the water’s surface. A UV shirt designed for swimming can therefore be practical. Families should nevertheless check whether it fits tightly after getting wet, shifts out of place or could lose protective effectiveness through stretching and wear.

Particular restraint is required for babies and very young children. The French Agency for Food, Environmental and Occupational Health and Safety, ANSES, considers direct sunlight unsuitable for this group because their skin is especially sensitive. Even high-quality protective clothing should therefore not encourage parents to expose infants or toddlers to the sun for prolonged periods. Shade and short periods outdoors remain essential.

When buying, families should consider size, comfort and care instructions in addition to UV labelling. A shirt that is uncomfortable or fits too loosely is less likely to be worn consistently. UV protective clothing is therefore an effective addition to everyday life when it remains part of an overall package: shade, covering clothing, head protection, sunglasses and sunscreen for all uncovered areas of the body.
