Founded in 2000, The Gro™ Company is a privately-held British nursery brand; it is best known for its award-winning Grobag baby sleeping bag, today the number one baby sleep bag brand in England and Australia. The company started the baby sleeping bag revolution with the introduction of the Grobag and actually changed the way parents put their babies to bed; now the majority of parents in the UK (over 95%) use baby sleep bags, making traditional top sheets and blankets a thing of the past. Each Grobag baby sleep bag includes a nursery thermometer, safe-sleep information and a user guide; the wearable blankets allow you to enjoy peace of mind when you put your baby down for a nap or for the night. The 100% cotton jersey baby sleep bags, often called wearable blankets, are machine washable and may be tumbled dry; they are made of with polyester filling and feature side zips and for easy changing.
