Tailored to contour the body in the cycling position; it clicks on, then follows your movement. RXQ The newly developed RXQ fabric is based on the legendary Assos RX textile. RXQ is a microfibre insulator fabric with two-way stretch, a soft touch and great breathability. It is unique because the brushed fleece inner surface is made of a hollow micro-Polyester blend with an air channel texture. This creates an insulating micro air cushion next to the skin. The overall volume of the fabric has been reduced and the moisture transportation properties have been improved, this means more body heat is retained and more comfort is achieved.
