In the 1970's an important milestone was born for Jollein. In Germany, mothers were buying sleeping bags for their babies. Wim Sr. Found that to be a neat thing. Holding the sleeping bag in his hand, he spontaneously thought that - with a few minor adjustments - the sleeping bag could become an ideal baby sleeping bag. He went to his sewing workshop and asked if they could make these adjustments. Two days later, the baby sleeping bag was born.
Jollein has become an expert in the field of baby sleeping bags. With years of dedication and innovation, we have perfected the art of crafting sleeping bags that prioritize both safety and comfort for your little ones. Our commitment to quality materials, craftmanship and attention to detail ensures that every Jollein sleeping bag provides the ideal cocoon for peaceful nights and happy babies.
TOG Guidelines
Checking for yourself and using common sense is the best method to ensure your baby sleeps safely. Additionally, there is a technical tool: the TOG value. This is a rating system for the insulating quality of bedding. The colder the environment, the higher the TOG value should be. Conversely, the warmer the room, the lower the TOG needed. TOG stands for Thermal Overall Grade, and the TOG value indicates how much body heat is retained in items like sleeping bags, blankets, swaddles, clothing, etc.
Note
TOG values should not be added together. This is because of the insulating air layer that forms between two layers, which always creates extra warmth. We advice parents to trust their instincts and use common sense.
