What dose writing on cap say?

To be honest, I can't make out what it says, it looks like gibberish. They're English words but they don't really form anything.

I didn't notice the string and the hat had a hole through it, how do i use this?😂is this what I really ordered?

I ordered that hat and the hole and strings purpose are so you can convert the hat into a face covering when the strings are open and when you want a hat you just pull the strings out and tie them like a shoe lace to keep the hole shut. It's basically 2 in one.

Is the material shiny?

This hats is thin and cool acrylic, a little shiny.

are these tight enough to use for sports? or would it fly off if you were running around?

I think it would be fine for sports. Very comfortable on me anyway. I have a few of these hats and they are on the fitted side. Definitely not loose around crown of head. I do not have a big head lol and they are comfortably snug. The back/slouch part would depend I guess on size of head and amount of hair as to whether that part is loose or not. I also wash mine in washer and dry it in dryer on like medium (don’t think you’re supposed to put in dryer but I like it staying fitted.) It can get pilly though so may want to do on delicate. Hope this helps
