Heat is transferred to the wearer through close contact between the garment and the wearer?s body. It is recommended that no more than one thin layer of clothing be worn under Synergy electrically heated apparel. Thick layers such as sweatshirts and sweatpants, increase the space between the garment and the wearer, decreasing the effectiveness of the heating elements.
