Most people do not like to feel cold. SEFAR PowerHeat is a new approach for bringing warmth extremely close to the surface that needs to be heated. Different temperature profiles are achievable in the fabric design, e.g. by adjustment of the heating wire and PET monofilament densities.
Quick heating up of this particularly light (around 60g/m2) and air permeable fabric is feasible. The fabric is washable and the circuitry is also completely insulated
