UV Clothing for Your Baby: When It Makes Sense and When It Doesn't
UV clothing protects baby skin from dangerous solar radiation. But when is it really sensible, and what should you look for when buying it?

Does a baby really need special UV clothing? In some situations it's the most effective protection there is; in others it's unnecessary. The difference is easy to spell out.
Why UV Protection Matters for Babies
Infant skin is very thin and produces hardly any melanin, the body's own sun protection. Sunburns in childhood significantly raise the risk of skin cancer in adulthood. In the first year, direct sun is therefore off-limits: protection runs through shade and clothing, with UV accessories added on top.
Why Ordinary Clothing Often Isn't Enough
A dry cotton shirt offers only about UPF 5 to 10, and less when wet. At the water, where clothing quickly gets soaked, ordinary cotton barely protects. UV clothing, by contrast, is made from densely woven, mostly synthetic fabrics that block radiation on purpose. The protection is given as a UPF, comparable to the SPF of sunscreen. UPF 50+ filters out 98 percent of the rays. When buying, check the certification: the “UV Standard 801” tests protection even when wet and stretched, exactly the state clothing is actually worn in at the water.
When UV Clothing Is Worthwhile
At the water it's especially recommended, because reflection intensifies the radiation. On vacation in the south and in high summer, ordinary clothing often isn't enough. In the stroller it helps when no stroller sunshade is installed. And in the carrier, the head, neck, and legs get more sun than is visible from above.
What Else Belongs With It
UV clothing alone isn't enough. It should be paired with a UV sun hat with a neck flap and, from about 6 months, sunglasses with a UV-400 filter, and above all with shaded spots under trees, shade sails, or UV tents. Sunscreen comes into play only from 6 months, mineral and SPF 50+, and even then only in addition to shade and clothing, on the uncovered areas.
And What About Temperature?
Synthetic fabric is less breathable. On hot days, combine UV clothing with light, airy pieces so your baby doesn't overheat. Checking your baby's neck helps here too. Many UV shirts are cut extra thin and can be worn wet; at the wading pool, the wet shirt even cools pleasantly.
Whether UV clothing makes sense on a given day is something the Wetterbaby app shows via the UV index for your location. From a UV index of 3, your baby needs protection.
