The top model in Sauer’s trouser collection is the "Comfort Extra". The difference and advantage compared to the Comfort Canvas shooting trousers already described lies in its canvas/caoutchouc combination. This caoutchouc material is extremely tough and retains its shape for years. The "Comfort Extra" trousers are therefore diagonally reinforced with this special caoutchouc material on the front in the lumbar area and in the seat area. It gives the shooter stability there where it is needed.
