- To offer you soft and comfortable products in practice, we use organic cotton. It is grown without chemical fertilisers, pesticides or GMO, reducing the risk of ground or water pollution. - By recycling plastic bottles to produce our polyester, we reduce the use of petrol-based resources while keeping the material's breathability in practice.

Resistance to wear and abrasion test: for example, we check that our fleeces do not pill using tests conducted in laboratories. Colour retention test: the colour fastness is verified to ensure that the colours do not bleed when coming into contact with saliva. Ageing test: repeated washing should not affect the fabric's properties, behaviour, thickness or appearance.

The environmental impact of the product is calculated based on its full life cycle using different indicators. An overall ABCDE mark is given to help you easily identify products with the best environmental performance by comparing similar products to each other (T-shirts, trousers, backpacks, etc). Decathlon is a voluntary supporter of this environmentally-friendly labelling approach. For more info:
