Episode 4 of Maker’s Mystery Box drops us inside the hallowed halls of Mystery Ranch HQ in Bozeman, Montana — the birthplace of some of the toughest load-haulers on Earth. The mission: hand John Bachman, mission designer, a sealed box of elite fabrics from La Terre, Korea lock him in with a sewing machine, laser cutter, and CAD software, and see if he can conjure a working backpack prototype before the 24hr clock strikes its last second.
