I've owned serveral of these shirts over the past few years. The are my shirt of choice - you can't beat the quality for the price. Take them out of the dryer and hang them up and you only need to give them a quick once-over w/ a iron and the look super sharp. Good heavy contruction.
I commute long-distance every week and ordered the wrinkle-free shirt to try and avoid ironing or trips to the dry-cleaner every weekend. Not only do they come out of the dryer ready to go, they travel well and at the end of the day, one could conceivably wear it again without all that many wrinkles.
