      Sensuede - Grade 3

      Sensuede was developed to be the best and most luxurious engineered suede available. The faux suede's soft touch comes from the use of breathable and wrinkle resistant recycled microfibers that are finer than a human hair but are extra-strong, resulting in a very resilient fabric. This material also was selected because of its environmentally sensitive content and manufacturing process.
