Make nighttime accidents feel like they never happened.With UnderJams®, your little guy gets to wear Bedtime Underwear just like he's used to, but with the dryness of Pampers Leak Protection™. That means, when nighttime accidents happen, he'll wake up dry and feeling a great sense of accomplishment. And it's all because UnderJams Bedtime Underwear have NightLock® technology, which makes overnight accidents feel like they never happened. Plus, UnderJams are made with cloth-like material and a low waistband so not only are they quiet, but no one will ever know your little boy has some nighttime help when he needs it most. UnderJams are available in S/M and L/XL.
