The hides of the ‘Easy Being Green’ collection are produced in a sustainable way and are safe for the environment and human health. The main difference lies in the fact that after tanning the leathers remain unsealed; the surface remains natural and open, instead of applying the often used plastic type coating. According to the producer the hides come from free-range grass fed Alpine dairy cows. They are not salted, but sent to the tannery on ice. The hides are vegetable tanned, all chrome-free. Dyed colours utilize safe materials, non heavy metal and low VOC dyes. For tanning, the producer uses half the water of conventional chrome leather. The water used is processed to the highest standards and returned to the water system where it is constantly monitored. The 100% bio-degradble hides are 1.4 to 1.6 mm thick.
