bolas al tercer lavado

hola, el tejido no deja color, pero le han salido bolas al tercer lavado

Buenas tardes Elena,

Gracias por dedicas unos minutos a valorar nuestro producto, lamentamos que no esté satisfecha con su compra. Anotamos su incidencia para mejorar el material del pantalón. Muchas gracias y un saludo



Está bien, aunque lleva pocas lavadas y todavía no sé si es un buen tejido. Queda bien puesto tanto niño como para niña.

Calidad regular

En tres lavados ya hicieron «bolas», sobre todo en las zonas de mayor desgaste. El algodón es peor que el de los pantalones básicos que cuestan la tercera parte. He comprado 2 y el ajuste de los tobillos difiere entre ambos

No se ajusta lo suficiente en la cintura

Me ha decepcionado porque lo he comprado para un niño de 9 años y no se le puede ajustar en la cintura lo necesario por tanto se le cae.

Hola Monica.

Muchas gracias por tu comentario.

Siento mucho que el producto no satisfaga tus expectativas.

Te invito a pasarte por la tienda para que mis compañeros de fitness te puedan dar una solución adecuada y puedas encontrar un pantalón que se ajuste a tus necesidades.
