Spiewak’s company started out in a one-room loft in Williamsburg, but grew in step with America’s own expansion. World War I marked the start of the firm’s business as a military contractor, producing wool coats, jackets, and naval breeches for the military. Spiewak introduced its first police jackets in 1923, outfitting the New York State mounted troopers. When World War II came, Spiewak supported the troops by delivering more than one million units of flying suits, bomber jackets, peacoats and other specialized gear. In keeping with its founder’s dedication to quality and durability, Spiewak has always made product innovation a central focus of its business, and it continues to this day.
