A product's ability to offer protection from the cold. It depends on the material's thermal resistance and how much air can pass through it. The higher its thermal resistance, the more the product retains the heat produced by the body while cycling.
Waterproofing 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.
A material with a waterproof rating of 2000mm resists the pressure exerted by 2000mm of water (which roughly corresponds to a 2-hour rain shower).

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.
