The main fabric is made of CORDURA® POLYCARBONATE, an original material developed by INVISTA. The base fabric is made of CORDURA® 305D polyester oxford, which is highly resistant to friction and tearing, and the surface is treated with polycarbonate, which is highly durable and has a slower rate of deterioration due to friction, abrasion, light resistance, and hydrolysis than regular PU coating, making it a waterproof and water-repellent material. The colors are the unique charcoal-colored "BLACK" made to order by CIE, "OLIVE" inspired by the sage green seen in European military wear, "GRAY NAVY" a low-saturation navy color inspired by the military navy of the Polish military, and "LIGHT GRAY" inspired by the pale gray of the all-weather coat used by the US Navy. The tape details are made of military-like nylon tape with a high-density woven ridge. The CORDURA custom woven name tag is CIE's original olive color, and the CIE original name tag is back satin woven on a traditional shuttle loom. The zipper uses CIE's original zinc die-cast YKK puller.
