ManhattanPortage [About the materials used].

Manhattan Portage's classic bags are made of the time-honored CORDURA® brand fabric, which has withstood the rigors of the world's toughest environments. Known for its exceptional durability, this fabric is used extensively in the outdoor and travel bag and workwear industries, and Manhattan Portage uses the highest quality 1000 denier CORDURA® Classic Fabric with a water repellent finish.

420D CORDURA® ECO

The strength and durability for which the CORDURA® brand is known are maintained, while the environmentally friendly nylon material is used to reduce air and water pollution.
Because it is made from recycled manufacturing waste recovered from factories, it is made in an effort to reduce the consumption of energy raw materials, reduce waste, and decrease harmful gases during incineration.
This fabric has an elegant luster and a light, soft texture while reducing environmental impact, making it both environmentally friendly and functional.
