Bayern Munich - Stadium Classic Adjustable Hat Black

Purchased this item as a gift for my husband. It has a very simple and clean look. I was disappointed when received it and the material the hat is made of was a surprise. It makes noise almost like windbreaker material when touched/moved to put on. I do not think he has worn it since I purchased it. There may have been a description of the material and I did not read it. Maybe they used this material to make the hat lighter and less hot.
