Commemorating Chris Gibbs' rarest Dunk pick-ups from his travels to Japan in the early 2000s, the Nike x Union LA Dunk Low '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.
