Children's wetsuits have the same properties as those for adults. However, children grow much faster, which makes it especially important to check whether the material still fits before the new season. The wetsuit for children should not be too tight, otherwise the freedom of movement is severely restricted, which quickly once clouds the joy of the sport. However, if it is too big, the water flows through it too much and the neoprene loses its insulating effect.
A good clue here is: If there are wrinkles at the armpits or in the crotch, it is better to take a size smaller.
Children usually prefer suits with back zippers, as these are easier for them to put on.
