Versatile and functional, the Sensor DOUBLE FACE SET WILD stands out as one of the most adaptable pieces in the Sensor range of underwear. A special construction of knit and the cut makes it possible to wear the clothes inside out with different thermal properties depending on how you wear them. The side marked as "plus" has a surface made of micropolyester silk, so it is ideal for warmer conditions. The side marked as "minus" is made of micropolyester staple, which makes it perfect for colder temperatures. The difference in thermal resistance between the two sides was laboratory-measured at 3.6°C.
