Blue Color is off from photos.
Size: One Size, Color: Blue
The visor is lightweight and feels comfortable however I bought this for the color of blue which was a shade off from the photos. I was expecting more of a royal or blue with a purplish hue. This doesn’t match the blue color I was going for. The visor is great otherwise.

Perfect for beach life
Size: One Size, Color: Light Purple
I got this visor about a week ago and love it. I’ve worn it to Busch Gardens (not on the rides of course), paddle boarding and to the beach. It’s soft and the elasticity is perfect, not too tight but does fine on a windy beach day. It’s sweat absorbing and dries quickly. I washed it in a bra bag in the machine and air dried it, no problems. I’ve already ordered another color!

LOVE these visors!
Size: One Size, Color: Navy Blue
I love these visors. They are the best that I have ever purchased. They are so comfortable and stay on your head without slipping and sliding while playing golf. I have three colors, and anticipate I'll be buying more colors soon!

Lightweight and comfy!
Size: One Size, Color: Fluorescent Yellow
Love this visor! Super comfortable and stays in place while running. Not super tight. I am a little worried it might stretch out over time and no longer fit, but as of right now, it is perfect. I ordered it in two more colors!

Too cheap for its price, not expecting it to last long
Size: One Size, Color: Rose Red
Flimsy and cheap feeling, you can find much better visors on Amazon for a few bucks cheaper. The bill is small, shorter than expected and it amuses me that the overly-long product “title” mentions being appropriate for men because I believe this visor would look ridiculously small on a normal man’s head. Honestly, fresh out of the package I wondered if I missed some detail about this being child sized. I do like that it is lightweight and that I won’t have Velcro stuck in my hair, though as an experienced seamstress and crafter I can already tell this is going to lose its elasticity FAST (as other reviewers have mentioned). I do love the color.
