I've worn this shirt on several flights and felt very comfortable in it. It doesn't crease and I think I look polished but relaxed in it. The fabric is very soft and fits me perfectly as I have broad shoulders and a smaller waist. It just has a nice tailored look and the fabric stretches easily. I've worn it in cool and hot weather and have never felt too cold or too hot in it. I think wool adapts to what you need to be comfortable with. I really like this shirt and will buy another color for my trip.
