The Moby™ D Winter White Fleece with Natural has the distinctive fabric panel in the center. The panel is created from cozy fleece. While all fabric panels add aesthetically to the Moby™ Wrap, the fleece provides additional warmth for your baby. The edges of the Moby™ D are seamed rather than over-locked, ensuring that the Moby™ D will hold its shape after extended use. We also made each end of the Moby™ D a different length so the knot would be at the side instead of the front or back.
