The HEFEL Cool pillow features an integrated fleece with PCM capsules (Phase Change Material) that supports temperature balancing and provides a pleasantly fresh feeling. The PCM technology helps compensate for temperature fluctuations and supports a pleasant sleeping environment around the head and neck area.
2-in-1: As the PCM fleece is integrated only on one side of the pillow, it can simply be turned over and used on both sides during cooler periods.
