Gambies are made from 100% preshrunk cotton in Pennsylvania. They are screen printed in Rockport, Maine and the company was originally from Bath, Maine! They are a one size fits all item that “grows” with baby. It begins as an infant sac. At 3 months of age, remove the drawstring and your baby can wear it as a cover up for the next few years. As the child grows, the sleeves just become 3/4 length to short sleeve. Use as an infant sac or after bath time. It can be a perfect sweatshirt type layer, anytime and ideal as a beach cover up. Gambies are a perfect gift that will last for years to come!
