Buen producto

Es idéntico a la foto. Buen producto

Buen pantalón

Son tal cual lo que estaba buscando

icon-circle-checkmark verified purchase

Es un pantalón relativamente ancho de la cintura, con lo que los niños algo rellenitos lo agradecen, a veces es difícil encontrar ropa con la que no se encuentren apretados, también diré que si los niños son delgados no se les caen. Cómodo y transpirable.

Perfectos para el deporte.

Son unos pantalones finitos para entretiempo. Ya los he lavado y ha superado la prueba, no le han salido bolitas. Cómodos para el deporte de los niños.

Cumple, pero no es especialmente resistente

Está bien como pantalón de chándal normal y corriente, pero me ha decepcionado porque no es especialmente resistente. Lo compré porque lleva un refuerzo en las rodillas, pero sólo ha durado 1 semana.

Our gym clothing is designed for kids aged 7 to 14: up to 5'8" for boys and 5'5" for girls

Our range is designed for sports activities at school or a children's gym. According to recommendations by the World Health Organization (WHO), children should do at least 1 hour of physical activity a day. The critical role of sport and its benefits for children's development and physical and mental well-being are proven: development of motor skills and agility, self-confidence, and belonging to a group

Physical education and sports activities allow children to burn off their energy and explore all the physical possibilities available to them: jumping, balancing, doing a series of movements and tricks. Moving, having fun, and enjoying sports with friends, all while following rules of life in a group, gym activities are accessible and have many benefits that both you and your child will enjoy!

The domyos product design process:

Our design teams work toward this single goal: providing a perfect balance of perspiration wicking, warmth and the need for stretch based on the needs of our young sports users. Your child will be able to choose their full gym outfit: T-shirt, tank top, leggings, bottoms, shorts, sweatshirt, and jacket.

A new sizing for children's clothing for physical education and sports beginning in january 2019:

We have improved the sizing on our clothing for ages 7 to 14. We present each product with its age range as well as the height of the child. We know that there are vast differences in height for children of the same age. Feel free to measure your child to see which model will fit them. We also offer an additional size for ages 14-15, to fit preteens: boys up to 5'8" and girls up to 5'5"

Did you know?

Our products are regularly tested and we make changes based on customer feedback.

The ideal lightweight and durable bottoms for doing sport cotton feel

After watching children do various gym and fitness exercises, we noticed that they spend a lot of time on their knees, which has an impact on the quality of our products. We decided to reinforce these areas so your child doesn't have to worry about getting holes when they kneel during their gym activities!
