The Duo Active Merino Body Baby by DEVOLD combines an outer layer of fine merino wool with organic wool from Argentina and an inner layer of ThermoLite®. This clever double structure ensures that your baby stays warm when it's cold and pleasantly cool when it's warm. ThermoLite® guarantees first-class moisture transport and is made from 100% recycled materials – sustainable and functional at the same time. The high-quality merino wool also offers excellent insulation and ensures a comfortable fit. Perfect for active babies who want to experience the outdoors even in the cold season.
