Awesome pants. They fit as expected and have a more dressy uniform appearance than some tactical pants (at least more so than those I have already). I especially like the expandable waistband that lessens the tendency of the pant to ride down or cut into my waist while bending, getting down on all fours, etc. The fabric is made (in part) from DuPont Sorona, a polymer fiber made from renewable resources (some crop that DuPont doesn't define). The description does state that the pants are treated with a DuPont Teflon finish, although it doesn't mention that it is Shield+, which is the specific Teflon product used.
