The main material is varistor nylon made in Japan woven with 66 nylon thread, which is also used for car airbags and bulletproof vests, and has excellent heat resistance, abrasion resistance, and tear strength. Some parts are made of highly water-resistant tarpaulin fabric, which is used as an industrial material. Although it is a one-tone black color, it has a stylish design with contrast by combining fabrics with different textures.

Details include internal card slots and money pouch, bi-fold design. D-ring allows attachment to other PORTER products.
