Durability of the components

Resistance to wear test: for example, we check that the fleeces do not pill using tests conducted in laboratories. Colour retention test: the colour fastness is verified to make sure that the colours do not bleed when coming into contact with saliva. Ageing test: Repeated washing must not alter the properties of the fabric, its shape, thickness or appearance.

Environmental measurements

The environmental impact of the product is calculated for the entire life cycle of the product and using different indicators. An ABCDE score is applied to help you easily identify the most environmentally-friendly products when comparing products of the same type (T-shirts, trousers, backpacks). Decathlon is a voluntary supporter of the environmentally-friendly labelling approach. For more information visit:
