Carhartt was founded by Hamilton Carhartt, whose surname became the workwear brand’s name.
Hamilton Carhartt established the company in Detroit in 1889. The business initially focused on durable work clothing, especially garments made from heavy cotton duck fabric. Its early identity centered on practical construction for railroad workers and other laborers who needed clothing able to withstand demanding conditions.
The Carhartt name is therefore a family surname, not a reference to a fabric, place or particular garment. The company later became known for work jackets, bib overalls, trousers and other utility clothing. Its products also gained popularity beyond industrial work, including among outdoor users and streetwear communities.
Carhartt Workwear and Carhartt Work In Progress are related but distinct parts of the brand’s modern business. The original American workwear operation remains associated with rugged clothing, while the WIP division presents more fashion-oriented adaptations. The founder’s surname is the same short name used by both branches.
