Too bad the Czech ones don't wear this, else I would have one with the symbol covered with something closer to what I practice. It sure looks like a great piece of clothing.
I have one of these shirts, have now for about a year. They are high quality and very durable. They aren't too scratchy, and they block wind very well. Its my go to outer shirt when winter/fall camping.

I have the green one, and it is a terrific bit of kit for the sale price. As soon as the red one in XL goes on sale for the same price, I will get one of those as well.
