Tranquility's Peach Mat Core Technology locks up moisture and keeps it away from the skin, reducing overall changes and helping you stay dry. Flexible, elastic leg cuffs fit snugly around the legs, providing a secure barrier to help prevent leaks. A plastic-lined, moisture-proof backing prevents leaks from moving through the diaper onto clothes or other surfaces. Refastenable tabs are adjustable, allowing you to easily reposition the brief for more comfort. Wetness indicator turns a different color, letting you know when it's time to change — and when it isn't.
