The belt bag is primarily crafted with environmentally conscious materials. The fabric is made from ECONYL® — a sustainable nylon yarn sourced from regenerated waste, that can be recycled and recreated. The black leather trimming with blue edges that refines the product is produced with CO2 neutral tanning process. All these choices reduce the environmental footprint compared to traditional materials and processes, making it an eco-sustainable product. A patch recalling the eco-sustainability of the line is applied outside the bag.
