Ultra Overnighters

Our New + Improved nighttime cloth diaper boosters are 3× more absorbent than before! Made from a premium blend of hemp and organic cotton, these soft, thirsty inserts are topped with a layer of moisture-wicking fleece to keep even the heaviest wetters dry and leak-free till morning.

Each Set includes 1 contour insert and 1 booster that can be used individually or together—so you can customize absorbency to match your baby's output. Pair with an Inner and Outer for overnight protection that lasts as long as your baby sleeps.

Also available as a Bundle (3 contours and 3 boosters) which just happens to be the perfect amount to match your diaper laundry schedule!

As soon as your baby starts sleeping in stretches of 6-8 hours, we recommend adding an Overnighter cloth diaper absorbency booster to their night diaper. This is the best way to prevent cloth diaper leaks.

Simply lay the Overnighter* inside your Inner cloth diaper with the fleece side facing up toward baby’s skin. Put the Inner and Outer on as usual.

*We recommend using the rectangular shaped booster on its own for newborns and light wetters, the contour alone for average wetters, and the contour and booster together for toddlers and heavy wetters.

Wash Overnighters with your Inners and Outers following the Esembly Wash Instructions.

Once your baby is sleeping in 6-8 hour stretches, we recommend having at least 6 (3 boosters and 3 contours) Ultra Overnighter absorbency boosters. You may need more or less depending on how you layer the nighttime diaper liners in your cloth diaper.

Ultra Overnighters can be purchased as a Set (1 contour + 1 booster) or as a Bundle (3 contours + 3 boosters).

The answer to the question "How many cloth diaper night inserts do I need?" can vary based on baby's age and whether you cloth diaper full-time or part-time. Let us help you determine exactly how many you need for your unique situation. Simply Take Our Quiz or Shop By Age.
