Forsite AM/PM are now available at Agecomfort. Has anyone tried them out yet? Might get a sample when I make my next order.
They are advertised as the, "most absorbent Adult Briefs ever." These briefs hold 4615ml in the mediums (27"-39.5"), and 5100ml in the larges (39.5"-59"). They feature an elastic waistband on both front and back, wetness indicator, and soft standing leak guards.
Agecomfort even made a dedicated video advertising these diapers. It can be viewed on their product page, or on YouTube.
