Pillows have a nice material on the outside that is slightly cool to the touch, with a quality zipper. There is a generous amount of memory foam inside the pillow, giving you a lot of room to customize the firmness. I also purchased the Tempurpedic Neck Pillows and have found myself using these instead from time to time due to the ease of adjusting the firmness. Overall I'm very happy with the purchase end definitely recommend the product.
