As a thin dude I've always struggled to find shirts that actually fit well. Most clothes (at least here in America) just don't fit well for people that have a smaller frame. These however, fit perfectly. They are snug, but not too tight that it gets annoying. The material is soft and stretchy, seems to be durable, and breathes well in the heat. These are the only shirts I buy any more, can't recommend them enough.
