These have a true flex waist which gives about an inch of wiggle room which certainly makes these pants comfortable.  The tapered leg gives it a bit of a more expensive tailored look along with the permanent crease down the front that more professional looking pants have nowadays.  Its a sharp, no-iron, summer-weight, flat-front professional dress pant.  Checks all my boxes.

If you can pick these up for 19.99 here like I did you got yourself a bargain.
