I bought these pants to work in as a volunteer EMT. They didn't even last three weeks! The fabric developed a small tear starting from my pocket were my knife clipped on to my pocket. It got bigger and kept going all the way down to my knee. So much for rip stop. The real crappy thing is this happened on a call while transporting a patient so I had to walk around the hospital with torn up pants until I could get out of there and go home and change. I would almost swear off Blackhawk after this but I have other pants from them that are good and I really like. But these pants deserve a pass. I was hopping that these were going to be like my old summer BDU pants from when I was in the ARMY. If your thinking that your way off the construction on these pants is very poor. The material is way to thin to be functional in the field.
