Soft cotton baby sleep sack with a hot air balloon and star design. Size: Large Includes the original storage bag. - Design: Hot air balloon and star print - Material: Soft cotton - Accessories: Comes with a storage bag - Size: Baby Thank you for viewing. I purchased this around autumn, but I preferred something a bit thicker, so I only wore this once and then stored it. L size is hard to find, but I think it's better for the baby to have some room, allowing them to move their hips more and reducing strain.
