300 Long-Sleeved Cycling Jersey - Black

A product's ability 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 in the heat produced by the body while cycling.

To determine whether a fabric is breathable, we measure its evaporative resistance (test based on standard ISO 11092).

The lower a fabric's resistance, the more it will let water vapour produced by the body escape, and therefore the more breathable it is.

For example: RET < 9 = extremely breathable fabric.

Machine wash at 30°C. Synthetic programme. Turn inside out before washing. 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.

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.
