Today we are listing a new Mens Poly / Wool Blend Brimmed Hat. The hat does not have a size on it but the inside but the inside opening measures 8" L x 6 3/4" w and has a pull string inside to tighten it. This hat was never own and still has the plastic insert I side. The brim is 12" in diameter. Very nice hat. If you have any questions please feel free to contact us.
