New + Improved Ultra Absorbent Nighttime Booster: For when your baby is sleeping in longer stretches and needs an absorbency boost.These super-absorbent inserts are 3x more absorbent than our original Overnighters. Be ready for leak-free, worry-free sleep.

Customizable Sets: The set includes one contour insert and one booster (the bundle includes 3x sets) that can be used individually or together—so you can customize absorbency to match your baby's output. Pair with your Esembly Inner and Outer (sold separately) for leak-proof overnight protection that lasts as long as your baby sleeps.

To Last As Long As Your Baby Sleeps: Each Overnighter is made from a premium blend of 55% hemp and 45% organic cotton, these soft, thirsty inserts are topped with a layer of moisture-wicking fleece to keep even the heaviest wetters dry, comfy and leak-free till morning.

Available in two sizes: Size 1 (7–17 lbs) and Size 2 (18+ lbs) to ensure a perfect fit and absorbency for babies and toddlers.

Can be purchased as a SET (1 contour + 1 booster) or as a BUNDLE (3 contours + 3 boosters) to match your diaper laundry schedule.

Simple To Use, Easy To Wash: Lay the Overnighter inside your Esembly Inner (sold separately) with the fleece side facing up toward baby’s skin. 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. To wash, just toss in with your regular diaper or household laundry.
