Are products tested before being sold?
Of course! All our fabrics must successfully pass rigorous lab tests to ensure your comfort and safety. We test them for colourfastness, resistance to repeated washing, perspiration wicking and more - we call these our "torture tests". And after that? Is that it? No, there's more. We then have sports users put our products through the ringer. We listen to and analyse their feedback to fix what needs to be improved. And only then is your sports clothing ready!
How we calculate our products' environmental rating.
The environmental impacts of our products are calculated for their entire lifecycle using various indicators. An "ABCDE" rating system helps you quickly see which products offer the best environmental performance. Use it to compare two similar products (T-shirts, bottoms, backpacks). Decathlon is a voluntary participant in this environmental labelling initiative.
