Poly Mesh Mustache Hat Sizer Pack - Black

Perfect hat size and sweat band. Easy to stick on and works perfectly.

There's a side-effect

I bought a hat in my usual size but it was too big. I read the Village Hat Shop section on sizing both before and after the sale. They recommended trying these. Yes, they make the hat fit. They also make the inside hat band stick out.

They need a 3 pack of sizes. Quality is top notch but it goes from too loose to too tight with just one.
