The adidas Original Cooling Neck is designed to be worn around the neck and filled with water or ice. I received two of these as a purchase bonus from a sports shop, but I already have this type and won't be using them, so I'm offering them for sale. They are brand new and unused. - Brand: adidas - Color: Blue - Product Name: Original Cooling Neck - Instructions: Included - Design: Neck-worn type Thank you for looking.
