Desde que lo probó mi hijo no quiere otro pantalón, así que tuve que volver y comprarle alguno más de color azul. El está cómodo y para mí es lo más importante.

Muy cómodos

El peque está tan a gusto con ellos que hemos comprado los mismos en azul marino y negro. Son de género espumoso y bastante calentitos.

Cómodos y calientes

Son unos pantalones de material espumoso, muy cómodos y bastante calentitos. El peque está muy a gusto con ellos. El tallaje es bastante pequeño, pero no he tenido problema porque ya lo imaginaba. Me pasa con todo lo de las marcas Decathlón. Por ejemplo, mi hijo tiene 5 años y la talla que usa es la de 7-8 y le quedan perfectos. De hecho son tan cómodos y están tan bien de precio que los hemos cogido en negro y en azul marino.
