When I first started an old technician told me we were on our knees more than a preacher. I have a drawer full of perfectly good pants except the knees are worn through. My wife has always been after me to wear knee pads but they are just to awkward and uncomfortable. That little gardners pad JW described works pretty good. I really like the idea of those pants with the knee pads except paying that much I would want the material to not wear through quickly.
