These pants are geared towards an auto technician. The fabric is durable, double knees, and some give around the waist. Kneeling in gravel is not bad at all. Way more durable than your standard cotton/poly uniform pants. Hitting them with the slag from a grinder isn't going to leave holes. I feel like my legs are protected. My only complaint is that I would prefer to have 2 covered pockets on the thighs (duplicate the left pocket on the right leg). I paired them with a Dickies scratchless belt. Overall, I think that they are great for the money.
