My husband's only reservation is that the collar is too stiff for a button-down collar. Past Bean's all-cotton button-down shirts were more comfortable and required very little ironing, even without wrinkle resistance.
I just oredered another six and they hold up great in my very dusty sweaty work locations. The only imaginable improvement would be to offer them in fitted style for those of us 50+ keeping up the valiant battle against the bulge.
The shirt is more than wrinkle-resistant. I have two LLBean wrinkle resistant shirts from a couple years ago, and this one is better. I would almost call it wrinkle proof. It never never gets ironed and it always looks great. It's good for you and who ever does your ironing.
