Pyrenex was founded in 1859 in Saint-Sever, at the foot of the Pyrenees, as a family business specializing in down and feather processing. For over a century, the brand perfected its techniques for working with natural down, producing duvets, pillows, and sleeping bags. Since the 1960s, Pyrenex has been creating its own outerwear collections.

Pyrenex’s aesthetic is inspired by French craftsmanship, alpine style, and functionality. The brand’s jackets and parkas are known for their minimalist design, lightness, and exceptional insulation, thanks to unique down sourced from ducks raised in the harsh Pyrenean climate. Pyrenex combines traditional techniques with modern innovations, making its products popular among both mountaineers and city dwellers.

The brand is recognized for its responsible manufacturing and support of ecological initiatives. Collaborations with leading designers and participation in fashion shows have brought Pyrenex to the international market.
