Great Product

Great product, however it will be good to improve on the variation of sizes available. It's either too big or too small for some kids. Otherwise, great product.

Easy to put on and take off after swimming. Haven't stress-tested it in the sun, but my baby is comfortable in it. There hare 3 buttons at the back just below the neck to make putting on and taking off easier.

Additional Product Information


Main fabric: 82.0% Polyethylene Terephtalate, 18.0% Spandex

Protection for kids

Baby's skin is very sensitive to the sun, because infants' defence systems only become effective after the age of 3. For identical exposure, the effects of the sun are two to three times stronger on a child than on an adult. It is therefore important to protect them effectively.

Behaviour in the sun?

Although this UV-protection T-shirt provides protection from the sun, other factors such as reflections (from water, sand, etc.), heat, time of day, and so on, must be taken into account. Wearing this T-shirt does not exempt the wearer from following the relevant advice: wear sunglasses, regularly apply suitable sun cream, wear a hat, stay hydrated, etc.

What does upf 50+ mean?

UPF is a sun protection factor (Ultra Violet Protection Factor) and is standardised worldwide. It defines the protection level of a fabric and more precisely the proportion of UV rays it lets through. To meet the standards, it must block at least 95% of UV rays. UPF 50+ means that the fabric blocks at least 95% of UVA and 98% of UVB rays.

Product testing

Long-sleeved UV-protection T-shirt developed and tested by our design teams in Hendaye, France. The components used for this product are laboratory-tested to ensure the best possible quality and durability.
