Heattech pieces can be layered to your heart’s content without ever adding bulk, making them the perfect embodiment of Uniqlo’s LifeWear philosophy, which is all about creating clothing that is at once functional and beautiful to improve consumers’ day-to-day without ever compromising on style or accessibility. “We draw up pieces keeping customer feedback in mind and then produce samples. After that, we have fittings—usually at least three but sometimes up to five or six—to get to the point where everyone is satisfied,” explains Yukihiro Katsuta, group senior executive officer at Fast Retailing (Uniqlo’s parent company) and head of research and development at Uniqlo. “We pay a lot of attention to the details, which is why I say our price point is affordable but our process is luxe.”

The Japanese brand, which is celebrating its 40th birthday this year, has also become famous for its sought-after collaborations with high-profile names, such as Marni, J.W.Anderson, Marimekko and Jil Sander. Most recently, British designer Clare Waight Keller (formerly of Chloé and Givenchy) was announced as the company’s creative director following the fall/winter 2023/2024 launch of her Uniqlo: C collection, a sub-label of elevated essentials.

We also have Waight Keller to thank for the introduction of a new addition to the Heattech family: a buttery cashmere blend that feels like heaven on the skin. It’s yet one more example of how Uniqlo continues to revolutionize the way we dress during the coldest months, proving that toastiness and elegance don’t have to be mutually exclusive.
