This merino wool sleeping bag is buttery soft and temperature regulating, keeping your baby or toddler comfortable throughout the night. 

Get better sleep while at home, traveling, or camping - a closable seatbelt opening allows for easy transfer between stroller, car seat, and crib.

If your overnights will be around 63°-70°, simply layer over your child's long-sleeve pajamas or base layer. If the temps will be around 71°-77°, layer over short sleeve pajamas.

- Temperature regulating: made with super-fine and supremely breathable merino wool, it helps keep your baby warm when it’s cold and cool when it’s warm
- A safer alternative to loose blankets: helps your baby stay covered through the night, replaces loose blankets in the crib, and promotes back sleeping
- Travel friendly: a closable seatbelt opening allows for easy transfer between stroller, car seat, and crib, so you can keep your baby’s sleep routine intact while on the go

Works for any season

I was buying so many sleepsacks as my baby grew and as the weather changed from colder to warmer that I finally decided to invest in Woolino ones. It’s super nice, thick, comfortable material and long enough to fit my baby for a long time!
