Based on the two super fibres an ultra-light and breathable fabric has been created. NATTWARM™ fabric is twice as soft as cotton and 4x more breathable. Despite the light softness of the fabric it will keep you as warm as other fabrics up to 50% heavier making it the best thermal pyjamas to avoid being cold at night. The fabric has been tested both in flat testing and torso testing by independent testing institutes.
