HEATTECH thermal underwear and clothing for women

Keep warm with HEATTECH: thermal underwear and clothing technology from Japan. This innovative fabric absorbs and retains body heat to keep you warm. Fibres one tenth the width of a human hair trap air to prevent warmth from escaping, while wicking away moisture from the body to keep you dry. These ultrafine fibres provide a smooth feel against the skin and can even neutralise odours to keep you feeling fresh. Not just for thermal underwear, our HEATTECH functionality is also available across a range of other clothing and accessories to keep you warm through winter and beyond.
