    What is HEATTECH

    Learn all about our thermal technology

    Keep warm with HEATTECH: thermal 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.
