Features of the product

We want a maximum number of sports enthusiasts to benefit from thermal insulation suited to the outside temperature and level of sport, without compromising on lightness. We rigorously test long-lasting quality components in the lab and in the field, to guarantee you warmth and a lighter weight.
Directions for use
To make the most of your hi-tech undergarment, it is important to check that all your equipment functions well together. The aim of an undergarment is to evacuate moisture from your body to the exterior. This means you also need breathable upper layers. In case of strenuous activity, dressing too warmly can make you feel cold, because perspiration is not eliminated and remains in permanent contact with the skin.
A mark to compare the environmental footprint of various products
The product's environmental footprint is calculated for its entire life and with various indicators. A score of A, B, C, D or E is provided to help you easily identify the most eco-friendly products by comparing products of a similar type (T-shirts, trousers, backpacks).

    Highly recommend the base layers

    Purchased these for my 4 children’s put under their school pe kit. My son (11) also wears his top and bottoms running in the cold weather and he is very happy with them.

    I am about to purchase some more for my girls as they have taken up football. Would definitely recommend this product, fantastic price and does what it should do.

    Satisfied customer

    I bought these for my grandson to wear when he is playing tennis during the winter . He finds them warm and easy to wear without requiring another layer during the coldest of evenings.

    Wed’ze children’s base layer

    I have always been happy with decathlon but unfortunately these children’s base layer trousers didn’t survive their first wash. One leg completely disintegrated. I would post a photo if I could.
    Very disappointing.
