Our Sleep Bag Swaddler is an all-in-one sleep system that comforts your baby from the newborn stage to the next. Made from our signature bamboo made from rayon, our patent-pending sleep bag swaddler functions as both a swaddle and a 1.0 sleep bag. The attached swaddle wrap features a Velcro closure for a secure and adjustable fit, and is fully removable once swaddling is no longer recommended. There's also a removable elastic loop that is fastened with a snap closure that can be placed around the bottom of the sleep bag. The additional step of tightening the sleep bag helps for little ones who haven't fully grown in to their new sleep bag yet. Underneath the wrap is our award-winning sleep bag.
