Available for immediate purchase. Purchased around March 2021 and used for 3-4 months. Stored at home since then. Size: S 【Super Easy & Lightweight】Simply put it on like a T-shirt and put the baby's legs through! No need to fasten Velcro or buckles. Weighing only 200g, it's 1/4 the weight of a typical baby carrier and is ultra-compact. It's so light you'll forget you're wearing it, and it fits easily in a bag, making outings much easier. Easy to wash and dry. 【Comfortable & Stylish】Unlike conventional baby carriers that support the baby's weight only on the shoulders, this carrier has a unique structure that covers the entire shoulder, evenly distributing the weight concentrated on the waist and shoulders. It also minimizes the burden on the waist and pelvis from the waist belt. Stretch air mesh is used on the back for breathability. While fulfilling its original functions, the simple design doesn't interfere with mom's fashion. 【Perfect for Getting Baby to Sleep】The soft and moderately elastic stretch fabric gently wraps the baby. It provides a sense of closeness similar to when mom holds the baby in her arms, and the baby sleeps very well. Also known as the "sleep-soundly" baby carrier. There are no unpleasant sounds like Velcro or buckles that might wake the baby. Let's put the baby to sleep without hurting your wrists. 【Safe & Secure】Safety certified as a baby carrier by international certification bodies (American ASTM and Korean KC). Certified by the International Hip Dysplasia Institute as a "baby carrier that helps healthy hip development." The fabric passes the KC standards for children's underwear. Can be used for newborns up to 20kg.
