Addendum: My husband wears the cap less than three months (September, October and November) and it is already very faded by the sun - of the autumn sun! The Olive has given way to an earthy hue. That should not be. My husband she wears at work, because it does not matter. He could no longer go out so ...

The washing has not changed the color. The sun is the color now so faded that the former olive cap now looks ausgbleicht sandfarben. But my husband she wears when working outdoors because the color does not matter, and for that she is super.
I would the cap - to work - again buy ... but by no means in black ... maybe equal in beige, which saves the fading :-)
Due to the poor color fastness only three points ...
