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.

A breathable, opaque sports bra with a cotton feel for physical education and sports activities.

This sports bra was designed to offer perfect coverage for all girls doing sport. It has a round neckline that doesn't gap when leaning forward, a muscle back to highlight the shoulders and improve freedom of movement. The length was designed to keep you covered at all times. Lined for improved opacity. Mesh zones for better ventilation at the back. Go easy when putting it on - sports bras are always a little tricky to get on.
