I wish the adult-sized Dickies were made as well as the boys' sizes!!  Unfortunately, they do not seem to be (at least not any that I've found).  My son goes to a school where they have to wear uniform pants in navy or tan, and I could get away with purchasing 4 pairs for the year (though this year, we've had to trade up because of size rather than wear)!  He went every year without outgrowing the pants (because of the flex waist).  I could buy them a bit long at the beginning of the year.

I love how these wash, though I did hang them to dry if they had a stain that did not come out right away.  They held their shape and did not pill or fade much at all.

ONE time (only once) he blew through the knee in one pair (because he had a surprise basketball game during lunch).  I called Dickies (because they guarantee the pants - I thought I would see if this was true).  I was told to either send the pants in to the company or to find a local Dickies store (which we happen to have somewhat nearby).  I took the pants in and they were replaced at no charge!!

This year he grew out of the size 20 - this style (flat front) does run a bit small.  We purchased a pair of the adult Dickies and were unhappy with many aspects (wash, wear, etc.).
