Our gym textile collections for children aged 5 to 14 years:
Our textile range has been designed for physical and gym activities from low to high intensity (trampolining, stepping, circuit training, core training, stretching, etc.). Ideal activities to keep your child fit and healthy, allowing them to progress further: jumping, rolling, climbing, core training, crawling, keeping their balance, etc.
The Domyos design process:
Our teams work with this single objective in mind: maintaining an ideal balance between softness and breathability for our young sports users. Did you know? Our models are tested regularly and we adapt them based on customer feedback.
Your upside-down movements finally work with your clothes!
After studying the things that held people back during gym activities, we noticed that a common cause of concern was having your back or stomach exposed because of the way the clothing was designed. If you try doing a headstand, you'll see what we mean! It inspired us to come up with this 2-in-1 T-shirt so that you can slip the longer part into your bottom half (shorts, leggings, trousers, etc.) and the problem's solved! No more stomach or back on show!
Dual use:
The product has also been designed to let you wear the T-shirt with the longer part over your other clothes, like a tunic!
