The latest item to hit the dedicated mastermind Japan ZOZO store is this full size backpack. The trekking-style pack is fully-featured with a solid lumbar support and chest straps, drawstring top, interior dividers, and compression straps all around. All of the construction and technical details are on-point – just as you would expect from Porter. With mmJ on design details, the bag is in all black, with polished hardware – including custom mastermind zipper pulls. The signature mmJ skull logo is placed top and center, and it gives the bag a kind of fatalistic mountaineer feel, rather the Tokyo Rocker look the brand usually channels. Finished with tonal Porter and mastermind patches, and a mastermind printed interior. The transcendent quality of the piece is that it is such a traditional mountaineering backpack, but crafted in a smooth monochromatic black. The full-size backpack is an established statement piece (all the way from Raf Simons x Eastpak to the BAPE Silly Thing Foot Soldier bag), and mmJ has a strong contender. Check the detail shots after the jump; the bag is available for pre-order now at mastermind Villa.
