It's now common in consumer soft goods to find apparel, tote bags, backpacks, and laptop sleeves made of material that was used for something entirely different in a previous life.
You can get shoulder bags made of discarded sailcloth and pillows sewn from Japanese shibori remnants.
The Swiss company has been making backpacks and messenger bags out of recycled truck tarpaulins since the early 1990s.
For the new line, Freitag has partnered with a Swedish company called We aRe SpinDye, one of several companies making synthetic yarns out of broken-down PET plastic bottles.
SpinDye's plastic yarn is woven into a textile which Freitag uses to build the inner lining and the more flexible parts of the bag.
Truck tarps make up the rest of the piece.
