We use cowhide, avoid scratches and grain, and use only clean parts. The length is slightly longer than a regular riders jacket to emphasis its luxurious style. Our brand is inspired by Japanese subculture in the 80s called Bosouzoku (youth biker group), and all the design was taken from original vintage clothing. Our clothes are sourced in Japan and are made by fine Japanese craftsmanship. When washing, please leave it to leather handwashing specialist.
