Machine wash at 30°C. Synthetic programme. Turn the garment inside out. Use minimal laundry detergent. Do not add softener. Line dry in a warm, ventilated area. Do not tumble dry. Do not dry clean. Do not bleach. Do not place on a heater to dry.

Product tests

Our team of product designers based at the B'Twin Village in Lille is continuously working to make cycling more comfortable for our users. Our obsession is to create products that meet the specific cycling needs of our users and eliminate hindrances to a good cycling experience.
We then test our products in the field, as we are convinced that only by subjecting them to real world conditions, such as those you experience on your bike, can we continuously improve our products

A rating to compare our products' environmental impact

A product's environmental impact is calculated for its entire life cycle using various indicators. Products are then given an ABCDE rating to help you easily identify the products with the best environmental performance (lowest impact) by comparing different products of the same type (T-shirts, bottoms, backpacks, etc.).
Decathlon voluntarily chooses to display the environmental ratings of its products.
