Uncompromising commitment to quality and sustainability drive Nau's mission to create cutting-edge designs that can be worn season after season. Sustainability begins with versatility-pieces that are stylish enough to stand out on urban streets Monday through Friday, but are technical enough for an ice-climbing expedition on the weekend. All of Nau's products incorporate natural and renewable fibers-mainly organic cotton, wool, cashmere, and recycled polyester-that are produced and processed in a socially and environmentally responsible fashion. The end result is a striking, high-quality item that you can feel good about buying and will enjoy wearing for years to come.
