Technical information


To ensure greater comfort in the saddle, we created this "Medium Density" chamois pad.
The fabric is soft and breathable. The reinforced zone is soft, with a density of 100 kg/m3 and a thickness of 13mm. The perforated fabric actively wicks away perspiration. The pad keeps you comfortable on rides of up to around 2 hours

Its shape

The shape of the reinforced areas (areas with thicker foam) was defined by tests on a sheet of pressure, designed by garment designers from a dummy moulding and approved after various trials and usage tests. This test, conducted on real cyclists, involves measuring the pressure points exerted on the saddle. The reinforced area covers contact points where pressure is greater. There is a dart at the front for a better fit.

Reinforced areas

The ischiums are well-covered, and the perineum is also protected. The reinforced area is relatively narrow between the legs to prevent irritation/rubbing while pedalling. Channels have been embossed into the reinforcements to provide greater flexibility.

Care tips

Machine wash at 30°C. Synthetic programme. Turn the garment inside out. Do not add softener. Hang to dry in a warm, ventilated place. 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 and 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.
