Commemorating Chris Gibbs' rarest Dunk pick-ups from his travels to Japan in the early 2000s, the Nike Dunk Low Union LA Passport Pack Argon takes cues from the 2001 Nike Dunk Low CO.JP Argon. It arrives with a tonal blue smooth leather construction that is wrapped in a tear-away, semi-translucent ripstop nylon covering. From there, a Union LA Frontman logo on the heel and "UN|LA" quarter panel tabs add the finishing touch.
