I had purchased the flex collar at the same time as this shirt.  Being a long term fan of Van Heusen shirts for my business needs, I am equally impressed with this shirt as well.  5 stars for both as it is easy to were both shirts.  Comfortable, convenient when cleaning, easy to care for, and classy in appearance.  I received a request for a promotion while wearing this shirt.  They asked me...to step up and take control.  sloppy clothes do not get you that experience.
