Abrasion and friction resistance test: for example, we carry out laboratory tests to check that the fleeces do not pill. Colour fastness test: we check colour fastness to ensure that colours do not bleed when coming into contact with saliva. Ageing test: repeated washing must not alter the fabric's original properties, including its shape, thickness or appearance.

The product’s environmental impacts are calculated over its entire life cycle using various indicators. An overall score from A to E is given to help you easily identify the most eco-friendly products by comparing products of the same type (T-shirts, trousers, rucksacks, etc.) with each other. Decathlon is committed to displaying the environmental information of its products. For more information: http://sustainability.decathlon.com/
