Is a normal T-shirt enough for children's UV protection?

No. A light cotton T-shirt has a UPF of only 5–10, meaning up to 20% of UV rays penetrate. A certified UV shirt with UPF 80 under UV Standard 801 lets less than 1.3% through, even when wet or stretched.

What does UPF 80 mean for children's clothing?

UPF 80 means the fabric only lets 1/80th of UV radiation pass (less than 1.3%). Compared to UPF 50 (which lets 2% through), UPF 80 offers a much higher safety margin for sensitive skin.

Isn't UV clothing too warm for children in summer?

Quite the opposite. UV clothing made of Polyamide-Elastane is lighter and more breathable than cotton. It moves moisture away from the body and dries in 10-15 minutes, preventing overheating better than cotton.

Why is UV Standard 801 better than other UV standards?

UV Standard 801 is the world's strictest test. It measures protection on fabric that is wet, stretched, and used. Other standards often only test the new, dry state, which doesn't reflect real-world use.

How long does the UV protection in children's clothing last?

In high-quality clothing like hyphen, protection is physical (based on weave density). It doesn't wash out or fade and lasts as long as the garment itself, even with frequent washing.

Children's UV Protection

They play outside. Their skin never forgets.

Children's skin is more active in the sun than any other – and yet less protected. What parents need to know about UV protection in childhood. Based on 25 years of experience.

Why Children's Skin Reacts Differently

Your Children's Natural Protection is Not Enough

Children spend up to three times more time in the sun than adults. At the same time, their skin is not yet fully developed: Melanin production – the body's own UV protection – only works reliably from puberty onwards. This means: during the years with the highest UV exposure, the skin has the lowest natural protection.

Important to Know

UV damage in childhood is the strongest risk factor for skin cancer in adulthood. The skin stores every bit of UV damage – even without a visible sunburn. The German Cancer Aid warns: Children need special UV protection because their repair mechanisms are not yet fully mature.

UV Shirt vs. T-Shirt

Why a Normal T-Shirt Fails in the Water

UV Shirt UPF 80

UPF 80 even when wet (UV Standard 801 tested)
Snug fit, no water resistance
Dries in 10–15 minutes

No re-application of sunscreen needed under the shirt

Cotton T-Shirt in Water

UPF 3–5 when wet (hardly any protection)
Flaps around, creates water resistance
Takes 2–3 hours to dry
Absorbs salt and chlorine
Becomes heavy, hinders swimming
Chafes against the skin when wet
Sunscreen underneath washes away

What does this mean for your child? Children don't wear UV shirts brand new and dry in a lab – they wear them wet in the pool, stretched while romping around, and washed after every beach day. That is exactly where the protection must work. UPF 50+ is only measured in new condition. UPF 80 according to UV Standard 801 guarantees protection under all conditions that matter in a child's daily life.

25 Years of Pioneering

Since 2001: UV Protection Out of Conviction

When hyphen was founded in 2001, UV protective clothing was practically unknown in Germany. Sunscreen was the standard, textile UV protection a niche. hyphen turned this niche into a category – and from the very beginning relied on the strictest standard: UV STANDARD 801 with UPF 80.

25 years later, awareness for textile UV protection has grown. But our core conviction remains the same: Children deserve the best protection, not the cheapest. Tested under real conditions, not just in a lab. Sewn in Europe, not at the other end of the world.

25 Years

Pioneer for UV protective clothing in Germany

UV STANDARD 801 since day 1 The strictest UV testing standard – tested wet, stretched, and used. No compromise, since 2001.

UPF 80 – Always Highest protection factor. Less than 1.3% UV transmission. Not as a premium option, but as our standard.

Pharmacy Approval The only provider of UV protective clothing in Germany with approval for sale in pharmacies.

Sewn in Croatia 550 km from Munich. European production with transparent conditions. No 20,000 km sea route from Asia.

Other providers came and went. Trends shifted. But the UV protection that children's skin needs hasn't changed in 25 years. UPF 80 according to UV STANDARD 801 – that was our conviction on day one, and it remains so today.

From Baby to Adult

Protection That Grows With You

Many providers of UV protective clothing only cover baby sizes up to 116 – which corresponds to about 3 years. After that, parents face a problem: new provider, different standard, unknown quality.

hyphen offers UV protective clothing for the entire family – from size 68 (babies) to XL (adults). Everything according to UV STANDARD 801 with UPF 80, everything sewn in Croatia, everything OEKO-TEX tested. The same standard, whether your child is 6 months or 12 years old.

And when children get older and ask their parents "Why do I have to wear this?" – the answer is simple: Because the whole family wears the same thing. Same protection, same standard, same trust.

UV Protection for Children – Parents Ask

Yes – and significantly more. All hyphen products offer UPF 80, tested according to the strictest standard worldwide (UV Standard 801). UPF 50+ is the industry standard and hyphen exceeds it by 60%. While UPF 50+ is only tested in new condition, UPF 80 according to UV Standard 801 guarantees protection even when wet, stretched, and after use – exactly how children wear their clothes.

From birth well into puberty. The skin's own protection – melanin production – is not yet fully developed in children. Dermatologists recommend UV protective clothing for all children who are regularly outdoors, especially between 11 AM and 3 PM.

No. A light cotton T-shirt has a UPF of only 5–10 – meaning up to 20% of UV radiation gets through. When wet, protection drops further. A certified UV shirt with UPF 80 according to UV STANDARD 801 lets less than 1.3% through – even when wet, stretched, and after many washes.

UPF 80 means the textile only allows 1/80th of UV radiation to pass through – less than 1.3%. In comparison: UPF 50 allows 2% through. Especially for children's skin, which reacts more sensitively, UPF 80 provides the greatest protection margin. At hyphen, UPF 80 has been the standard for 25 years – not marketing, but conviction.

On the contrary. UV clothing made of Polyamide-Elastane is lighter and more breathable than cotton. The material wicks moisture away quickly and dries in 10-15 minutes. Children are less likely to overheat in it than in a traditional cotton shirt.

The UV STANDARD 801 is the strictest testing standard worldwide. It measures UV protection not just on new, dry fabric, but also when wet, stretched, and after use – i.e., under real conditions. Other standards only test the brand-new state. hyphen has consistently tested according to UV STANDARD 801 since its founding in 2001 – for 25 years, without exception.

In high-quality UV clothing, where protection is created by the weave density of the fiber, the UV protection lasts as long as the garment itself. At hyphen, the protection is physically anchored in the fiber structure – it doesn't wash out or fade. The UV STANDARD 801 test explicitly confirms protection in used condition. This is crucial for children's clothes, which are washed especially often.
