Damart thermal clothing

Damart is a French-British heritage brand most famous for inventing Thermolactyl, a unique fiber known for its warmth and insulation properties. Founded in 1953 by the Despature brothers in Roubaix, France, the brand revolutionized winter clothing by providing lightweight yet warm thermal undergarments. Over the decades, it has expanded from a mail-order business into a global retailer of fashion and home textiles.

While the brand originated in France, its manufacturing processes are now distributed across several locations to serve its global customer base. The brand remains under the stewardship of the founding family's business interests, ensuring a focus on the technical textile innovation that made it a household name in Europe and the United Kingdom.
