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.

Cute and comfortable, though a little big without tightening a bit
Size: One Size, Color: (100) White / White / Reflective
Love the bright color and material. It fits a little big at first but has the ability to tighten quite a bit so it should be fine like it is for me. I just have a smaller head. It has great coverage. Feels comfortable as well.
