The Lee 101, introduced in 1925, became one of Lee’s best-known workwear products.
Lee developed the 101 line during the company’s expansion from general merchandise into purpose-built clothing. The number became associated with durable denim garments designed for workers, including jeans and related workwear. Over time, the 101 name continued to be used for classic Lee denim products and heritage-inspired versions.
Lee’s workwear background helps explain why the 101 line became important. The company had already established experience making practical garments before jeans became a mainstream fashion item. Its products were marketed for durability, comfort and use in demanding working environments.
The Lee 101 is sometimes confused with Levi Strauss & Co.’s 501, another famous numbered jeans line. Both numbers are strongly associated with denim, but they belong to different brands. Lee’s signature heritage number is 101, while 501 is the well-known Levi’s designation.
