I was worried about polyester, as i know it is a fashion faux pas even though i am now too old to care about such things.  the practicality of the pants trumps other considerations for me.  they look nice.  the comfort waist is a plus.  they do not appear to be wrinkle free after getting them out of the dryer, but when you put them on the wrinkles disappear.  we will see how durable they are over time...

Quick update: They do appear to be durable.  These are now my favorite pairs of pants for work, and I'm glad Amazon is now offering more colors. I'm back to order the Slate, and I'm increasing the rating to five stars.
