Crafted in Japan, the highly sought after Oki-Ni Master Piece is one stellar backpack. Forged from 420d thick PU coated nylon, on both sides, it ensures protection from the elements. The main compartment fastens with a Velcro sealing flap, plus three extra clasps, but there is a side zipper for fast access. The front pocket is protected by a waterproof zip and the padded back section makes it a joy to carry while the reflective trims will keep you visible come nightfall.
