The Erzstef Arkona Teco Duvet is a temperature-regulating and moisture-absorbing duvet. It is suitable not only for people who tend to sweat in bed but for anyone who desires a balanced sleeping environment. Both during the day and at night, the human body continuously produces and releases heat through its own thermoregulation to maintain an optimal comfort climate. Generally, bedrooms are becoming warmer, which is due not only to global warming but also to improved building insulation. The Arkona-Teco bedding can counteract this trend. By using PCM (Phase-Change Material), known as RUCO-THERM PCM, you can combat nighttime overheating and enhance thermal comfort. The heat regulation works like an ice cube in a glass of water: when the ice cube melts, it absorbs heat and cools the water.
