Cotton shirt

Excellent price for cotton t-shirt

Tiny, and thin

Sizing is way off. Firstly there's no 6-7 only 5-6 or 7-8.. but the 7-8 we bought is TINY! Size up at least 1 size. The material has barely any stretch and is really thin too.


Decent holds form after washed

The 5-6 is skin tight on my just turned 5 year old, the sizing is really off and not worth returning for the price

Not true to size

I've ordered size 7-8 years and it's so small my 8yo couldn't even fit head through it! Quality of the t-shirt seems OK for the price.

Additional Product Information


Main fabric

  • 100% Cotton

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.

Eco-designed product

First, our supplier collects cotton fabric scraps during production to turn them into fibers. Our spinner then produces a yarn containing 30% of these recycled fibers. This yarn will then be used to make the main component of our printed mottled gray T-shirts.



Product testing

These tests are regularly performed by an independent laboratory and allow us to ensure that our quality standards are always upheld. This product has undergone washing and drying tests to verify that it retains its cut and color.

Superior quality. Unbeatable prices.
