Race short-sleeved cycling base layer

Developed and tested for cold weather, this base layer will protect you from those early-season cold temperatures when road or mountain biking.

Breathability

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.

Care tips

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.

Product tests

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 so as to eliminate things that get in the way of their rides. 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.
