Sports clothing designed for kids and teens aged 6 to 14 5'8" for boys and 5'5" for girls

Our range has been designed for kids' indoor sports or PE classes at school. The World Health Organization (WHO) recommends that kids devote at least 60 minutes each day to physical activity. The role of sport and its benefits to the mental and physical development and well-being in kids and adolescents have already been well proven: development of motor skills and agility, self-confidence, and social inclusion.

What do we mean by educational gym and sports activities?

PE lessons and sports activities allow kids to unleash their energy and explore all the physical possibilities available to them: jumping, balancing, stringing together a series of movements, and doing tricks. While mostly practiced at school during PE, it can also be practiced in clubs or recreationally.

The joys of sport:

Sport offers numerous benefits for both kids and teens, from moving around to having fun and interacting with friends, all while learning how to get along with others!

The domyos product design process

Our design teams work toward a single objective: providing a perfect balance of perspiration wicking, warmth, and stretchiness based on the needs of our young sports users. Kids will be able to choose their full gym outfit: T-shirt, tank top, leggings, pants, shorts, sweatshirt, or jacket.

Find the perfect size for a kid or teen

Our sizing for kids aged 6-14 is evolving! We offer products by indicating the age range and height of kids. We know that there are vast differences in height for kids of the same age.
