Our toddler potty training underwear comes in a Double Gusset design that offers extra protection and higher absorption. They come with a ravel-resistant waistband, 4-way stretch fabric, and plush smooth fabric for optimal comfort. The bamboo and charcoal lining helps fight odors and bacteria, allowing the toddler to feel happy, secure, and cozy. The Double Gusset overnight undies still have the classic snug fit bikini design but with an added layer of protection for children who have occasional bedwetting at night and need additional protection. Now, parents don’t have to spend their nights constantly changing the sheets!
