PHENOMENON was established in 2004 by Takeshi “Big-O” Osumi, inspired by Japanese street, fashion, and music culture. PHENOMENON teams up with Masaaki Homma’s Mastermind WORLD for this latest collaboration. The Cross Loop Zip Detail MA1 Jacket offers a contemporary twist on the classic bomber jacket, with its cross design composed of zip pockets and Mastermind WORLD’s signature skull and crossbones motif.
