MATERIAL: Our Microfiber fabric is a favorite due to its amazing lightweight, soft and luxurious texture. This range is also ultra-strong, easily cleaned and water repellent. A soft touch combined with the richest of tones makes the Microfiber range equally at home with a day at the office or a night on the town.
