Our thermo cover ensures a comfortable and cooler journey for your child, even on the hottest days. It uses OUTLAST® technology to keep the skin temperature constant, reducing overheating and therefore perspiration for your child. This technology includes Thermocules™ that take in and store excess heat releasing it when your child needs it most. To use, simply slip it over your normal seat cover. The cover’s outer material is comprised of 100% cotton and is machine washable at 30°C.
