Sports clothing designed for kids and teens aged 6 to 14 172 cm for boys and 166 cm for girls

Our range has been designed for kids' indoor sports or PE classes at school.
The World Health Organization (WHO) recommends that children 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 children 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 children 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 practised at school during PE, it can also be practised 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!
