Cool Caboose is the newest and coolest child seat protector for strollers, wagons and car seats. Cool Caboose not only protects expensive and difficult to remove stroller pads, it actually helps keep your child's body temperature regulated. It is made out of a multi layered 3 ploly mesh material that promotes airflow. Along with this washable and airy material, its what is on the inside that sets Cool Caboose apart from every other seat liner on the market. The inside houses a semi-freezable, non-toxic "ice" pack that fits perfectly in a foam pouch to keep it cooler longer but mainly is in the foam porch because attached to the outside of this pouch is a cooling gel. The combination of these two cooling devise allows for the perfect amount of "coolness" to reach your babys caboose and back.
