- 365 days to return for members
- warmthComfortable and warm, perfect for occasional use.
- anatomic designIts great stretch guarantees optimal comfort
- moisture managementThe fabric wicks away perspiration
- Functions of a base layerYour body releases heat and perspiration as you ride. If you do not wear a suitable base layer, moisture management will be very difficult, preventing the regulation of your body temperature, leaving you wearing heavy, cold clothes, which feel very unpleasant. This 100 fast-drying, cycling base layer, made out of soft fabric, keeps you warm and comfortable during occasional rides.
- Product warmthThis is a product's ability to protect 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.
- CARE TIPSMachine wash at 30°C. Synthetic programme. Turn the garment inside out. 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.
- Product testsOur 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.

Ecodesign approach

Using this mass-dyeing process enables us to reduce CO2 emissions linked to the production of dyed textiles by at least 17% compared to conventional dyeing.

Our design teams are working to develop processes that will reduce the impact of a product, while preserving its technical characteristics. This reduction relates to the following indicators: climate change, air pollution, water pollution and resource depletion.

Using recycled polyester rather than conventional polyester reduces the CO2 emissions linked to the material by at least 17%.
