PIT

TWISTING DOUBLE PILOT or also English leather:
During the age of industrialisation, the English developed "English leather", a fabric made of only cotton, in order to protect the workers at the blast furnaces from flying sparks (and just incidentally to save the significantly more expensive ox-hide smocks).
The workers put the finishing touches on their smocks
by rubbing them with moist clay.
We produce these guild trousers in Germany.
