Bubou is made from the high-tech material Comfortemp®, which has even been tested in space. Tiny microcapsules store excess heat and release it again when needed — for a consistent temperature all night long. As a result, the baby sleeps safely and relaxed. The risk of overheating and sudden infant death is minimized! The sleeves of the sleeping bag are also removable so that it can be used all year round. The two-way zipper makes nighttime changing easier and is well hidden under a chin guard and protects the child's face and neck. The Bubou sleeping bag is made from high-quality materials from Germany. All substances are tested for harmful substances and comply with Oeko-Text Standard 100 and safety requirements EN 16781:2018 and are therefore a safe choice for children's health. The end user can therefore be certain that all textiles used are absolutely harmless to their child's health.
