These pants are a poorly constructed copy of the Job Man and Bjornklader euro work pants.
I wear both of the other brands daily at my work in a light industrial setting and reccomend them highly.  These pants could have been very nice if they were sewn in a workman like manner.  They look like I did the sewing (not good).
Job Man and Bjornklader (Google them!) both have better products for around the same price.
