The C17 All-Weather Saddle is constructed using the same vulcanised natural rubber top as seen on Brooks’ standard Cambium C17 but is also covered in a tough and durable Nylon cover. This means, that unlike the standard model that has a cotton cover, this All-Weather model does not absorb any water. It also offers a precisely tuned flex with no breaking in period and is ready for many years of intense riding and in all types of weather.
