Prevail AIR Overnight Briefs are the latest addition to the Prevail AIR Brief lineup. Using the premium features from our Next Generation Briefs, we’ve added the new breathable AirMax Layer to our Overnight Absorbency briefs. The new Prevail AirMax Layer takes Microclimate Care to the next level by helping decrease skin’s contact with moisture. The specially formulated breathable material traps wetness inside but air, heat and humidity escape, allowing the skin to breathe.
