A product's ability to protect from the cold. It depends on the fabric's thermal resistance and air permeability. The higher its thermal resistance, the more the product retains the heat produced by the body while cycling. This undergarment can be worn as a base layer under an anorak or long-sleeved jersey.

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 product's environmental impact is calculated for its entire lifecycle 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.
