Kid's Thermal Clothes

Of course! At decathlon.com.gr you will find a large variety of kids' thermal clothing (thermal tops & leggings) that keep children warm and dry during their activities in the cold. We offer soft, elastic models for play, school, and sports, as well as technical thermals for skiing and the mountain. Pair them perfectly with a kids' fleece, a waterproof jacket, kids' gloves, and a warm beanie for complete protection in winter!

Children can wear thermal base layers from preschool age (from 2-3 years old), as young children are more sensitive to temperature changes and get cold more easily. Decathlon kids' thermals are made of soft, hypoallergenic materials without irritating seams, offering total comfort, warmth, and freedom of movement even to our youngest friends.

For a thermal base layer to work properly, it must fit like a "second skin" on the child's body without squeezing or restricting their movement. To select the right size, consult the size guide of your desired product and take into account the child's height and age. Avoid buying a larger size "so it lasts for next year," as air gaps between the fabric and skin reduce thermal insulation and effective sweat wicking.

Absolutely! A thin thermal top or thermal leggings are the ideal base layer for very cold winter days at school. They wear comfortably under school tracksuits, jeans, or hoodies without adding bulk, keeping your child warm both inside the classroom and during playtime at recess.
