THE NORTH FACE PURPLE LABEL x Spiber Sierra Parka

Sierra Parka, one of the most iconic products of THE NORTH FACE PURPLE LABEL, receives a fresh makeover by nanamica. Kodenshi® down used in the insulation provides natural warmth by delivering the far-infrared radiation energy emitted by the human body back to the skin. Debuted in the 1970s as the first outerwear of THE NORTH FACE brand, Sierra Parka has become to be recognised as the standard of down parkas in the outdoor scene. This version is made with Brewed Protein™ fibers, an innovative structural protein materials that are regarded to be a new solution to numerous pressing environmental issues and risks, to become a more modern product.

Brewed Protein™ materials are fibers, films, and other types of materials that are manufactured through fermentation (brewing) of plant-based ingredients. This new class of material is created using Spiber Inc.’s proprietary technology platform that enables customized design and molecular engineering of nature-inspired protein polymers. These materials can offer alternative solutions to a wide range of conventional animal-based, plant-based and synthetic materials for various purposes, including textiles applications for the apparel industry.
