The Softest Organic Cotton Muslin Voile fabric Lightweight Wearable Sleep Sack replaces Coverlet / Blanket / Quilt / Rajai / Comforter for Babies & Toddlers. It is smooth & pliable, and does not scratch the baby's delicate skin, and allows them to sleep peacefully. It is further softened by a cotton Flannel fabric inside the Muslin layers, which gives it some thickness & a wooly feel. No loose fiber inside makes the product hypoallergenic. Using the best imported Organically grown cotton, our products are free of any pesticide or chemicals which may be harmful for Baby's skin and hair. The more you wash, the softer it gets! And the colors remain intact, minimum fading.
