Each Tzeltal community constitutes a distinct social and cultural unit with its own well-defined lands, wearing apparel, kinship system, politico-religious organization, economic resources, crafts, and other cultural features. Women are distinguished by a black skirt with a wool belt and an undyed cotton bloused embroidered with flowers. Their hair is tied with ribbons and covered with a cloth. Most men do not use traditional attire. Agriculture is the basic economic activity of the Tzeltal people. Traditional Mesoamerican crops such as maize, beans, squash, and chili peppers are the most important, but a variety of other crops, including wheat, manioc, sweet potatoes, cotton, chayote, some fruits, other vegetables, and coffee.
