First thing I want to mention was the prompt delivery of these pants after I ordered them. I am serving overseas and getting packages is not an easy task.
These pants are made with a denim "rip stop" like material. Very sturdy with double stitching on the seams. I wear a folding knife usually in my pocket and have worn the edge on a couple of BDU's. These pants have a leather protector sewn into this area to prevent this. I usually rip the crotch area out of my pants from the constant kneeling and odd positions I get into. The double stitch seams appear to be holding. The only draw back on these pants is that they do not breath due to the heavy material they are made out of. Any work environment over 100 degrees is a no go for prolonged periods of time. The other pants I wear are Woolrich, which I also highly recommend.
