A unique cloth made from Ripstop which is backed with black fleece. Fortis is renowned for using ripstop. It is a woven fabric made from a cotton polyester mix. It is woven using a reinforcing technique making them more resistant to tearing and ripping. Thicker reinforcement yarns are interwoven at regular intervals to form the square pattern. As this ripstop is backed with fleece, it has a slight stretch to it.
