A slim pouch worn under a shirt on a neck cord, with a lining that blocks unauthorized scanning of contactless cards and a passport chip. It holds a passport, boarding passes, cards, cash, a key and a phone.
Ripstop fabric that resists tears and snags with repeated packing and wearing
Waterproof construction keeps papers dry in sudden rain
Sits comfortably out of sight beneath clothing
