I found a foam visor with a coiled elastic band at a local store. There are many for sale on Etsy and Amazon. https://www.amazon.com/foam-visors-coil-bands/s?k=foam visors with coil bands The one I have weighs 0.65 oz/18.4 grams.

This is the perfect hat, especially if you wear a sun hoody. The way I typically wore this hat was with a pony tail or my hair clipped in back with a claw clip. I would use an orange fabric hair band or half buff to hold the small flyaway hairs away from my face, put my sun hoody hood over my head and then use the visor to hold my sun hoody on my head so it wouldn't blow off. I would loop the coiled elastic in back under my pony tail or hair clip.

Sometimes if the wind was really strong I would put the buff over the elastic to help hold it on. I'm not sure that was necessary. I found a string and tied it to the coiled elastic and I would use my sternum strap through a loop on the other end of the string string to secure the hat so I didn't have to think about it. I usually do this with chin straps on other hats. The visor never did blow off or fold into my face or anything under wind conditions. It was really secure and perfect.

The visor's bill provided ample shade for my face and my eyes. It's neither flat nor excessively curved like some caps are. Because it was a visor I could position it lower when the sun was lower to shade my eyes better or position it higher to see more around me.

One benefit to a visor over a cap is you can wear a beanie at the same time. You can put your hair up in a bun. If you have giant amounts of dreadlocks or an afro it'll probably fit better than a cap (I do not have dreadlocks or an afro.)

It came in lots of colors and prints at the store where I bought it. I was able to get a nice orange and purple batik print.

The only downside for me was that even though my head is pretty small, the elastic was pretty tight and the edge of the foam against my forehead took a while to get used to. But once I started putting the visor over a buff or over my hood that problem went away. You can loosen the elastic coil a little bit and I have no idea if they come in different sizes or not.

And of course if you are bald or don't have a sun hoody you don't get a lot of sun coverage for your head or neck.
