Aden +Anais cozy sleeping bags are four layers of muslin, making babies comfortably warm during cold, wintery nights. Designed to be worn over baby’s pyjamas, they ensure a safe night’s sleep by eliminating loose blankets. Muslin’s light, open weave allows a baby’s body temperature to regulate itself naturally helping to prevent overheating. These terrific sleeping bags offer the ultimate in breathability and softness, as the more the more you wash them, the softer they get. Each sleeping bag zips from the bottom, making nappy changes easy, and a strip of muslin over the zipper by baby’s face provides extra comfort. Available in a variety of sizes and prints to suit all babies. Comes beautifully packaged, they are the perfect transition from swaddling and make an ideal newborn gift.
