Women's innerwear

Take action against the elements with UNIQLO’s range of HEATTECH innerwear. Comfortably regulating your body temperature without the discomfort of bulky clothing, these tops and leggings cleverly use moisture released by the body to retain heat to keep you warmer in colder months. All HEATTECH products also feature moisturising Moroccan argan oil for maximum comfort during dry seasons. Crank up the heat in more challenging conditions with Extra Warm and Ultra Warm pieces and opt for cooling, breathable AIRism on warmer days.
