I had doubts about whether size 80 would be enough, but try on the pants, it looked fine. Unfortunately, we are then directly in the sand and have tried the jacket later. The fact is too small. In particular, the elastic band at the bottom of the jacket will be tolerated by my son in any way. The material feels comfortable and we have also noticed no unpleasant odor. We have had only mud pants with zipper and so I was surprised that no one here was my turn; but it proved to be a problem. In wet sand she held my son been dry and warm; the rain capability we have not yet tested in the glorious weather. What convinced me above all of the Oeko-Tex Standard.
