JACK BUNNY neck cooler. I bought this for golf, but I'm selling it because I don't use it. The storage case has an aluminum interior, so it has excellent cooling effects. I have stored it at home, so please refrain from purchasing if you are nervous about this. - Brand: JACK BUNNY - Product name: Neck cooler - Inner material: Aluminum vapor deposition material - Design: Swing Everyday logo - Color: Navy Thank you for viewing.
