What is the difference between Dickie's Industrial pants and regular pants?

I looked this up before I bought my most recent Dickies, and was saddened that there was no answer... So I bought both, and now I have an answer!

The answer is: the "industrial" (aka more expensive) dickies are WORSE! For two reasons:

The belt loops aren't as thick and are placed less intelligently (the two in front are too close together so you can't wear a buckle!).

Finally: the zipper is much shorter and less convenient.

Stick with the regular pants!
