Waterproofing 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 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.
Machine wash at 30°C. Synthetic programme. Turn the garment inside out. Use minimal laundry detergent. Do not add softener. Line dry in a warm, ventilated area. Do not tumble dry. Do not dry clean. Do not bleach. Do not place on a heater to dry.
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 vapour produced by the body escape, and therefore the more breathable it is.
For example: RET < 9 = extremely breathable fabric
When cycling, your speed greatly increases the sensation of cold. An outdoor temperature of 10°C will feel like 7°C when cycling at 25 km/h. A windproof barrier helps prevent air entry, subsequently reducing heat loss.
