Nice visor
Size: One Size, Color: Grey Six/Rose Gold/3
I bought it for trail running in the woods - keeps the glare off my glasses so I can see obstacles. It gets soaked really fast making it heavy but it's really week made and I love the colors.

Big fan of this visor!
Size: One Size, Color: Black/Silver Reflective/3
Ok. This visor is so breezy. The band is comfortable and perfect for the Houston heat! I love the rubber on the end of the adjuster. This means it won’t fray. It’s lightweight material, sizing is perfect, and fit is comfortable. Great value for the money!
