You ever got to close to the edge of something. Got hold of your pants and put that thin rip in them? Not enough to make a hole, but enough where you notice it and think it may open up? You know at the wrong time too. These don't seem to have that problem I can definitely feel the difference in this material from a pair of $19.99 pants. It's true you get what you pay for. I am happy with my purchase, highly recommended.
