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, the use of water is reduced by about 40% and the use of salt by 80%. After tanning, the water is recyclable. ChromeFree leather is used on the entire leather Kids collection.Coming from the State of São Paulo in Jacareí, this suede is a 100% vegan synthetic textile and an alternative to animalproduced suede. It is a nonwoven fabric made of microfibers that are needlepunched together and impregnated with P.U. resin. This solventfree process is less toxic than the ones used to produce classic synthetics suedes.
