Our luxuriously soft, 20.5-mircron, Hanna Mountain Merino® yarn is used for these beautiful heirloom Playground Beanies. The name, "Playground" refers to the amazing fact that these beanies will grow with your child. As an infant, simply roll the cuff. The hat will grow with your infant until their toddler years. The soft wool not only feels amazing next to precious baby skin but also helps to regulate baby's temperature. Another unique feature of this beanie is its lightweight nature. Babies and children find them so comfortable they forget about them and tend to leave them on their little heads. Check out our coordinating Baby Blanket to keep baby in full comfort!  Official age range is newborn to 4 years old.
