Japanese biotech venture Spiber Inc. and sports apparel maker Goldwin Inc. announced the launch in December of what they claim is the world’s first outerwear jacket made with protein material produced via microbial fermentation. The Moon Parka jacket will go on sale in a limited volume under The North Face brand at one of its shops in Tokyo for 150,000 yen ($1,400), with the pale gold-colored nylon-like material being used for its surface layer.
