I recently took this on a two week trip as my only dress shirt and I can confirm that it works as advertised. It stayed wrinkle free through my whole trip and I even got some compliments on the shirt. A few things though. First, I guess I am just not one of those people that can handle merino wool. I tried wearing this without anything underneath and I definitely feel it on my body. I could probably have dealt with it for a few hours but I wouldn't have been able to wear it all day like that. It feels like a thousand tiny kitten claws. I ended up having to wear a t-shirt underneath it. I am not faulting the shirt for this just more of warning for those that struggle with wool. This is not the miracle fabric that will change that. The second thing was that I saw the pictures of the models and they were like "so and so is 6' 3" wearing a medium" this made me think they run large and they definitely do not. I am 6' 1" and about 190 and admittedly I could lose a few pounds and I am not some young kid trying to show off his muscles but I got a large and thought it was too small and returned it for an extra large. I am including a couple pictures so you can decide for yourself.
