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

Physical Education and Sports allow children to get out their energy and explore all the physical possibilities available to them: jumping, finding their balance, 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 is accessible and has many benefits that both you and your child will enjoy!

The domyos product design process:

Your child will be able to choose their full gym equipment: T-shirt, tank top, leggings, bottoms, shorts, sweatshirt, or jacket.

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"
