Children's sports T-shirt

It's great, we bought another size. It has a large enough opening for the head and is flexible, so the child can take it off and put it on himself.

Product testing

When we design our products, we select fabrics and inks that are not harmful to children, and accessories (buttons, drawstrings, rhinestones, etc.) that cannot be swallowed. We make sure our fabrics are not toxic if put in your child's mouth. As well as these standards, we consider your child's safety when designing every aspect of our products. These little details make all the difference!

Child development

We design our products with the support of a physiotherapist to understand how we can make kids more autonomous through our clothing. ”The challenge is to prevent kids from becoming discouraged. You need to give them actions that they can see are possible so that they'll repeat them until they become automatic and something they can use more generally,” explains Agathe, our partner physiotherapist

Helping kids achieve their aim of dressing themselves

How do we help them out? With easy-to-close zips, a wide neck so they can get dressed on their own without being stuck in their jumper, visual markers so they get their clothing the right way around, and more! Thanks to this little helping hand, your child will gradually get to grips with dressing themselves like the big kids.

Baby gym

Part sport, part game, and part chance for your little one to explore the world! Baby gym is the starting block for budding champions. It supports your child's psychomotor development while they have maximum fun! Kids aged 1 to 6 can take part in obstacle courses made up of special child-friendly apparatus.

The benefits of baby gym

Does your child do baby gym? Did you know that this fun sport helps children develop their motor skills? Through a range of activities and by discovering new sensations, your little gymnast will learn to balance, develop their motor skills and coordination and learn all the things they're capable of doing! It is an excellent way to help them learn self-confidence.

What to wear for baby gym

To be comfortable, your child can count on Domyos products: T-shirts, bottoms, leggings and even a jacket! The aim is for them to be comfortable without having to pull their bottoms up or their T-shirt down all the time. The technical features vary depending on your child's level.
