Discover your secret weapon for a truly restful sleep with these recovery pyjama shorts. Nattrecover is made from Microlyocell, a high-tech fibre made from eucalyptus and heat-activated minerals that convert excess body heat into natural far-infrared energy. This fibre is not only cooler than linen, has better moisture management than cotton and is softer than silk, but is also environmentally friendly and sustainable. The minerals contained in the Recovery Collection are made from a special mineral matrix that meets the highest standards of environmental, health and safety.
