AQUATHERMIC components have technical characteristics that reduce thermal shock when entering the water. They reduce the amount of water absorbed and, as such, the chill due to the evaporation of this water on the surface when the child is out of the water. This wetsuit also helps to reduce the intensity and the time it takes for the child to feel cold when by the pool.

Baby's skin is very sensitive to the sun, because children's 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. Therefore, it is important to protect them properly.

UPF is a worldwide standardised sun protection value (Ultra-Violet Protection Factor). It defines the textile's degree of protection, and more precisely, the proportion of transmitted UV rays. It must keep out at least 95% of UV rays to meet the standard. UPF 50+ means that the textile blocks at least 95% of UVA and 98% of UVB.

Although this baby UV protection wetsuit 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 shorty suit does not exempt the wearer from following the relevant advice: wear sunglasses, regularly apply suitable sun cream, wear a hat, drink regularly, etc.
