It is a comfortable pillow for dogs and cats. When going for a walk outdoors with a pet stroller, place this in the stroller with a liner by using the snaps on the edge to cool down your dog's body temperature. This special material called "COOLIER" has an immediate cooling effect and amazing breathability! It absorbs sweat and at the same time, releases heat very quickly. The fabric is usually used to make bed sheets for human. The special weaving technique called "TRIPLE JACQUARD" makes the fabric even thicker and softer when touching. No artificial dye has been added to it to maximize its cooling effect as well as to make it safer for sensitive skin.
