León de los Aldama

León has a large leather industry, making shoes, boots, belts, jackets, and other leather accessories for national and international markets. The leather industry earned its inhabitants the nickname of "green belly" (panzaverde in Spanish) because of the green tainting in the workers' bodies resulting from treating leather. Its hotel and service industry make it an important commercial center with numerous options for entertainment, gastronomy, leisure activities, arts, and recreation. It is also considered one of the most environmentally friendly cities in Mexico and has a high number of cyclists, in part because of integrating a network of bike lanes into the SIT system.
