OAKLEY GOLF Oakley Golf New Ear Muffs I bought these because I thought I had lost my old ones, but I found them, so I'm selling these. These are unused and were purchased last weekend, but please understand that they have been stored at home. The size can be adjusted by sliding the arm on the back. Also, the inside uses soft fur, making it an essential item for warmth in winter golf scenes. Material: 100% Polyester Size: Free Size
