We heard pleas for more insert options so Thirsties has added two more inserts to join our original Stay Dry Duo Insert: Natural Duo Insert and Stay Dry Natural Duo Insert. The Natural Duo Insert is comprised of a 3-ply 100% organic cotton upper insert snapped to a 5-ply 55% hemp/45% organic cotton lower insert. The Stay Dry Natural Duo Insert shares the same construction, but the upper insert, which is placed closest to baby's bum, is topped with a layer of stay-dry, stain-resistant microfleece. As with our original Stay Dry Duo Insert, these inserts are available in size one and two for a more customized fit.
