Back in 1993, brothers and graphic designers Markus and Daniel Freitag were on the hunt for a handy messenger bag – one that was heavy-duty, functional, water-repellent and large enough to protect their designs. Inspired by the brightly colored trucks rumbling along the cross-Zurich highway across the road from their apartment, they decided to cut their own messenger bag design from an old truck tarpaulin supported by a strap taken from second-hand car seat-belt webbing – and finished with an edging cut from an old bicycle inner tube.
