The sweatband on the inside of the visor only goes up half way and is not sewn in on the top to secure it in place so it exposes the interfacing which is thin. On the other visors the sweatband goes all the way up and is sewn in. The sweatband material in the other visors is much cushier than this one. Lastly, the sweatband material makes my forehead itch. Other than the construction and materials used in the sweatband, the visor is well made and the color is as pictured.

A good buy

Size: One Size, Color: Power Pink

First, love the color. It's very comfortable. I was concerned cuz I have a small head but very adjustable and it fits. It's breathable my head didn't get so hot like it normally does. I think I'll be ordering another in another color

Perfect Visor

Size: One Size, Color: (001) Black / Black / Reflective

I bought this thinking I wouldn’t like it. I was so wrong. This is lightweight and the perfect fit. What a great value. It’s so comfortable on your head and the vent on it was a great idea. Adjusts easily and just a great buy.

A great sport visor

Size: One Size, Color: (100) White / White / Reflective

My head is small so a lot of visors don’t fit because of the Velcro. This is perfect and the ability to wet it for coolness is great. Love it for tennis.

Great for running

Size: One Size, Color: (001) Black / Black / Reflective

Hat fits well and worked great for my marathon. The Velcro doesn’t pull on my hair.
