Aalfs Manufacturing Company

Aalfs Manufacturing Company, owned and run by the founding Aalfs family, just might have a gene for the jeans business. The company designs, makes, and markets clothing (primarily jeans and denimwear) to big-name retailers nationwide. Clients include J.C. Penney (since 1943), American Eagle, Tommy Hilfiger, Gap, Old Navy, and even Harley Davidson. Aalfs also makes and sells its own 4 Stroke brand of denim apparel. Founded in Iowa in 1892 by H.A. Baker and renamed the Aalfs-Baker Manufacturing Company in 1929, when Wilbur Aalfs held the presidential title, the apparel manufacturer officially became Aalfs Manufacturing Company in 1959.
