Dreaming Big since 1973: Over 50 years of baby sleeping bag expertise

Welcome to the world of Jollein, where we've been creating the most beautiful, safe, and comfortable baby sleeping bags for over 50 years. Our journey began in 1973, and we haven’t stopped innovating since. Jollein has become the expert in baby sleeping bags. With more than half a century of experience and innovation, we’ve mastered the art of designing these essential products.

The birth of a brilliant idea

In Germany, moms (to be) were busy shopping for baby sleeping bags. Wim Sr. found this inspiring. While holding one in his hands, he had a brilliant idea: with just a few small changes, this could become the perfect sleeping bag for babies. He immediately went into his sewing workshop and brought his idea to life. Just two days later, the baby sleeping bag was born!

50 years of excellence and passion

Since 1973, Jollein has been on an impressive journey. We've grown into the go-to brand for baby sleeping bags, and our decades of experience and innovation have led to a perfected product. We understand how important a good night’s sleep is—for your baby and for you. That’s why we pour love and expertise into every product, so the whole family can enjoy some well-deserved rest.

What is TOG and why does it matter?

TOG stands for Thermal Overall Grade and measures how insulating bedding is. It helps you choose the right sleeping bag based on the room temperature, ensuring your baby always sleeps comfortably and safely. The colder the room, the higher the TOG rating should be—and vice versa. This system helps create the ideal sleep environment for your little one.

Tip: Never add TOG values together. The air between layers provides extra warmth, which isn't reflected in TOG ratings. Trust your instincts and use common sense alongside these guidelines.
