The Marvels AIO is a one-size diaper with an attached inner soaker. It is designed so that the attached soaker agitates out when being washed, allowing everything to be well-rinsed, and thereby eliminating the need to stuff the diaper. After everything is washed and dried, a simple tug pulls the diaper right-side out and at the same time pulls the soaker back inside the pocket. The closure at the waist is a single row of snaps and the rise is adjusted with a series of vertical snaps on the diaper front. The waterproof exterior is PUL, the interior is polyester fleece, and the attached soaker is absorbent polyester micro-terry.
