Ability of a product to offer protection from the cold.It depends on the material's thermal resistance and air permeability.The higher the thermal resistance, the more the product keeps the heat produced by the body while cycling.

Waterproofness is a fabric's ability to prevent rain water from passing through.
A fabric's water repellency is its ability to make water bead and/or run along its surface. The garment soaks up little or no moisture, dries more quickly, and doesn't become heavier. Water repellency can also make it more difficult for its outer surface to become dirty. Water repellency is obtained by applying a treatment to the fabric's external surface.

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, like the ones you experience on your bike, can we continuously improve our products.
