Environmental impact

C rating - Comparison: men's waterproof jacket - technical details


Waterproofness is a fabric's ability to prevent rain water from passing through. A fabric's waterproofing is determined by measuring its resistance to the pressure exerted by a water column, measured in mm (test based on ISO 811 standard). The higher the pressure, the more waterproof the fabric. Material with a waterproof rating of 2000 mm resists the pressure exerted by 2000 mm of water (which roughly corresponds to a 2-hour rain shower).


To determine whether a fabric is breathable, we measure its evaporative resistance (test based on standard ISO 11092).
The lower its resistance, the more the fabric will let water vapor produced by the body escape, and therefore the more breathable it is.
For example: RET <9 = extremely breathable fabric.

Product tests

Our team of product designers is based at the B'Twin Village in Lille (France). All year round, we conceive and develop new products that are easy to use, look great, and have the technical features needed for your cycling experiences.
They are then mercilessly put to the test by users in the field, as we are convinced that only by subjecting our products to real world conditions, such as the ones you will experience on your bike, can we continuously improve them.

A rating to compare 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 products having 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.
