Alpha Industries is an American clothing manufacturer founded in 1959 in Knoxville, Tennessee. The company was started in order to manufacture flight jackets on a United States Department of Defense contract. The start of the Vietnam War in 1960 meant a sudden increase in demand for military clothing and Alpha's growth rapidly accelerated. By the end of the 60's Alpha emerged as a leader in manufacturing, especially the now famous nylon flight jacket, the MA-1. Then, during the 70's, Alpha began to sell commercially and grew into an international commercial seller of American military style and fashion apparel.
