Chrome made their first messenger bag over 15 years ago. They needed a quick-release buckle for getting a fully loaded bag off quickly. To maximise durability and weatherproofness, every Citizen is made twice. The inside liner is made with military-grade, 18-oz truck tarpaulin. The outside is made with abrasion-resistant, 1000-denier CORDURA® Brand fabric. The Chrome Black Ops Citizen is inspired by the same all-black Chicago flag patch worn by tactical units throughout the city. Like the patch, the Black Ops Citizen uses all black for the entire bag, with the exception of the grey stars and d-panel.
