【Comfortable Sleep Environment】 This swaddle is designed to help babies sleep soundly. The stretchy fabric gently wraps around the baby's body, supporting a comfortable sleep. 【Easy-to-Use Zipper Design】 The zippered design makes it easy to put on and take off. It's also hassle-free for diaper changes, allowing for stress-free use. Mesh material is used in some areas to prevent stuffiness and support comfortable sleep. I opened it, but I never used it and have been storing it.
