Cute comfortable, and perfect for Golf!
Size: One Size, Color: Black, Size: One Size, Color: Black
I love this black visor! It is lightweight, comfortable, and provides great sun protection while I’m out on the golf course. The soft elastic headband feels gentle on my head, stays in place, and doesn’t leave any marks, even after wearing it for several hours.
The moisture-wicking material does a great job of keeping sweat away, helping me stay cool and comfortable during hot rounds. The classic black color goes with everything, and the visor has a cute, sporty look.
If you’re looking for a comfortable visor that offers excellent sun protection without feeling heavy or tight, I would definitely recommend this one!

Very good, comfortable, breathable, and easy to maintain
Size: One Size, Color: Black, Size: One Size, Color: Black
I really like this visor and use it often for workouts and outdoor activities. It’s easy to wash and doesn’t lose its fit like Velcro visors that stop sticking after a few washes. The material is lightweight and breathable, making it great for running, pickleball, or golf without trapping heat. The one-size-fits-all stretch fits comfortably and stays in place without feeling tight. It’s comfortable enough to wear for long periods and doesn’t cause pressure. Plus, the clean and stylish design makes it look good both during workouts and casually.
Pros
Easily washable (no Velcro to wear out)
Breathable and lightweight for sports
One-size-fits-all with a comfortable stretch
Secure fit that doesn’t slip
Looks stylish
Cons
Doesn’t have a very solid shape if you prefer a stiffer visor

A great running visor hat shades the face and keeps sweat out of your eyes.
Size: One Size, Color: Orange
I usually run in really hot and humid conditions and generate a lot of sweat, so wearing a visor allows the body heat to escape through my head and also acts as a sweat band. I needed replacements and decided to give these a try. They were beyond my expectations. The visor design is very light, thin fabric but the bill is very rigid. You can't adjust its fit and it was very tight when I first put it on. However, after an hour of running, it was very comfortable. It has a full sized bill and provided full shade coverage for my face and had no problems with sweat in my eyes. The visor construction was such that it held sweat really well. The design also caused the sweat to travel down the bill and drip off of its edge instead of down onto my face. I only wrung it out a couple times during a very sweaty runs to get the sweat out of the band.
I love these visors, they are a great value for their quality, and have already bought a couple more.

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.
