The bovine ChromeFree leather is smooth and light. Coming from farms located in the south of Brazil (Rio Grande do Sul), it undergoes an innovative tanning process where no chrome, heavy metals, or dangerous acids are involved.By simplifying the tanning process, the use of chemicals and energy is limited. Water use is reduced by approximately 40% and salt by 80%. After tanning, the water is recyclable.
