Cordura is considered to be the most durable material for making professional panniers and bags. It is often used by army, secret service and by most reputable outdoor equipment producers. The material is resistant to mechanical damage. A special weave stops a possible tear. In addition we treat the Cordura with a permanent impregnating agent creating a coating on the inner side of the Cordura with a polymer resin with PVC. An outside coat- Teflon® makes water drip off the surface without soaking in.
