Stylist Notes O.T leather undergoes a mechanical beating process that makes it fine and bendable. Tanned in Brazil, it uses less dyes than Veja's  conventional leather. VEJA sources O.T. leather from the Uruguayan Pampa, a region renowned for the quality of its leather and livestock farming. The cattle from which O.T. leather is obtained are not sourced from deforested areas and are not exposed to pesticides, GMOs, chemical fertilisers, or antibiotics.
