After a set liquid dose has soaked into the pad, a stack of filter papers and a weight are placed on top for a fixed time, and the gain in filter paper weight is the rewet. Low rewet means a drier feel against the skin. Topsheet finish, acquisition layer structure and core capacity all influence it.
Rewet came in at 0.3 grams with the new ADL, half what the old one gave us.
