The cap was as described in the product description. The color 'diablo/dark grey" was a little different than I expected. But not game breaker. The cap has an airy mesh base. There is a nylon over layer from the brim to the back of the cap. This layer protects the top of you head as well as forehead from the sun. The mesh and the separate over layer provides a very well ventilated cap. The brim is firm and of adequate length to provide shade from the sun. It fits well and is adjustable.

Just what I was looking for. Protection from the sun. Yet a very light and well ventilated cap. It can also be washed. All in all a great "outdoors" hat for the summer months.
