I have been buying Carhartt for my husband for a few years now and he loves them. The duck dungaree double fronts are awesome too. He works in chemicals and sometimes gets them on the pants, Carhartt pants last the longest before getting holes ate into them front the strong chemicals. I buy them regularly and would recommend to anyone. They have a thick canvas like material that lasts for a very long time and have a side pocket and little loop for  a cell phone and/ or tools if needed...
