Envelope Swaddling Sleeping Bag for Newborns & Premature Babies

Cosy fleece-lined swaddle for 0+ months – ideal for car seats, carrycots, pushchairs, cribs, and more.

The Envelope Swaddling Sleeping Bag is a soft, supportive cocoon designed to keep newborns and premature babies warm and secure in their earliest days. Perfect for the first few months, its gentle shape cradles your baby while allowing natural leg movement for healthy development. Lightweight and versatile, this fleece-lined swaddle fits seamlessly into daily routines, whether you’re at home or on the go.

Specially crafted for comfort and adaptability, the Envelope Swaddling Sleeping Bag wraps your baby in warmth without restricting movement. The clever footmuff-style design gently hugs your baby’s body, while leaving the legs free to move naturally – supporting comfort, circulation, and healthy hip positioning.

Made from a breathable blend of 50% cotton and 50% elastane, the outer fabric is light and soft, while the fleece-lined interior provides essential warmth and insulation. This swaddle adapts to a wide variety of baby gear including Group 0/0+ car seats, carrycots, cribs, and pushchairs – making it a true all-rounder for newborn care.

Featuring secure Velcro fastening on the flaps, the Envelope swaddling bag ensures your little one stays snug without disturbing their rest. It’s also compatible with the Nest baby carrier included in the Groowy car seat system.
