What is Brude Protein™ Fiber?

NANAMICA's cruiser jacket is based on the hunting jackets of the 1980s. This outerwear is the star of the show. It looks minimalistic and urban. However, a closer look reveals details that cater to the wearer, such as large flap pockets with gussets, a detachable hood, and raglan sleeves.
Such a cruiser jacket is, of course, excellent in terms of design and function, but the most important thing is the new "Brewed Protein™ Fiber" that has been adopted this time. In Japanese, this material is "Brewed" and "Protein. In Japanese, the words "brewed" and "protein" mean "artificially created protein fiber.

BROOD PROTEIN™ FIBER" is a material that can be created through microbial fermentation. Let us introduce the process of creating such an innovative material with illustrations.
