I love wearing baseball hats but hate all the logos that come with most of them. I have had an Arc'teryx for years. The logo was the same color as the white hat and disappeared. It was a breathable one for running but didn't scream running hat. Over time, the hat discolored with sweat stains and I have been looking for something to replace it and sadly Arc'teryx doesn't make that hat anymore. So, I ordered 3 of these Kuhl hats in white, blue and black hoping that I could have 3 different colors to rotate through. Sadly, they all fit slightly differently and they do run on the big side. My son and wife were my fashion consultants and each of the 3 "same" hats had a different fit and as a result a different look. I put it to just slight differences during manufacturing. That and the fact that I shave my head which means that I don't have a big head of hair that makes up the difference in slight size differences. The hats varied by how close the sat to my ears and the shape they took on the side and top when I had them on. So, I am keeping the one hat that fit and returning the others.
The one that fits is great. You should note that it sits deep on the head and goes all the way to the top of my ears. The others touched the top of my ears, a difference of a couple of millimeters. I have a bigger head, size 7-5/8, so I fall into the large size on helmets, hats, etc... Also, the hat has a stiff mesh lining on the front facing part of the "dome" to keep its shape. It is structured/styled like a baseball hat versus a trucker's hat but it does have that stiff lining in the front that you find in some baseball hats and all trucker hats. In the hat that fit me, that stiff mesh couldn't really be detected because that hat "fit". In the others, you could tell that it was there by the way the hat pulled back on the sides.
So, the one that fits gets a 5 star review. The ones that didn't get 3 stars since they are great hats but didn't fit. In all, it averages out to a 4 star review. For $30 a hat, it would be great if Kuhl could dial in the sizing for these things.
I really enjoy the light, breathable material while also blocking sun (better than farmer caps). However, the geometry and profile of the cap is odd. My family tells me the shape looks weird and not natural. And the sides come down too low.
