Designed specifically for bedtime and naptime, this clever solution can’t be kicked off—which means a more restful sleep for the baby and the parents! It features a 2-way zipper that opens around the bottom for easy diaper changing and a sleeveless design that allows babies to move their arms freely. Insulated with light Dupont Sorona, it keeps your baby safe and warm. Manufactured at an OEKO-TEX Standard 100 certified factory, you can feel confident that our sleep bags are free of toxic chemicals and always safe for your baby.
