Details that make the difference:
Longer at the back to keep your back covered at all times (grooming, jumping, etc.)
A RATING TO COMPARE PRODUCTS' ENVIRONMENTAL IMPACTS:
The product's environmental impact is calculated over its entire life cycle using several different indicators. An overall rating (ABCDE) is generated to help you easily identify those products which have the best environmental performance by comparing products of the same type (T-shirts, trousers, backpacks, etc.).
Decathlon voluntarily chooses to display the environmental ratings of its products.
