I don't think you want soft and flexible. You want rigid and durable. Check out DuraFlap. They are probably the best in the industry and are used all the time in the off-road community. Plus, you can get them in a variety of widths and lengths. There's so much winning with DuraFlap.I'm glad I found this thread. I'm about to order mud flaps at 4WheelOnline. I'm changing my tires next week, and I've decided to add mud tires for additional protection from particles. I just have to look for a soft, flexible yet durable mud flaps.
