These are my favorite pants.  I don't think they make them anymore.  Overall, these pants are very well made and should last a lifetime.  The material is some sort of rip-stop cotton, and very hard wearing.  The pockets are edged at the back w/ some sort of binding to protect against wear and makes getting into the pockets easier.  Pop fasteners are sturdy and reliable,  The leather touches on the front right pocket is cool and help protect against wear from keys.  Work-class work wear.
