Taking baby out can be major production. With a sac at the ready, you put the baby in a short or long sleeved onesie and then zip the baby into the sac. Voila! You are ready for the world — all the time keeping baby warm, but free to move their legs. So easy to change out a diaper too! A blanket, hat, socks and burp cloth complete this adorable outfit for getting out and exploring the world! Also available in solid mint and sky with white printing. Sac available in one size only.
