The black and red chequered jackets and shirts favoured by gun-toting hunters from cartoon character Elmer Fudd to several former Presidents, known as Buffalo Plaid in the trade, were a Woolrich invention.
Roswell Brayton Jr or Roz, as he is called, is Chief Executive of Woolrich, the oldest wool mill and maker of clothing in America.
The company was official provider of blankets to Northern troops which kept the Union army warm during the American Civil War.
Brayton said Woolrich was the first company to install zipper in men's trousers.
Woolrich no longer makes many of the clothes that bear its trademark. Sourcing of garments from China, India and Pakistan is being presently carried out, Brayton said.
John Rich, who built Woolrich mill and town, was a wool-comber from Bradford. Rich built his first mill in Plum Run, Pennsylvania, in 1830 selling socks, blankets and other woollen goods to loggers in hill encampments.
Woolrich presently is just a shadow of its former self. Ten manufacturing plants have been sold off with one mill remaining, said Brayton.
He employs 650 workers at present whereas his father had employed 3,500 when Woolrich was at its peak.
