Happy Heinys Pocket Trainers We've redesigned our training pants with your busy toddler in mind! Snaps can be added for ease in messy clean ups and to make stuffing easier. Snaps will be added to one side or the side can be sewn shut for our older bed wetters. Makes it easy for potty training as they can pull up and down with the elastic waistband. This is also good for older children with bed wetting issues. Quick on and off. Like our diapers, we use custom milled fleece in our trainers and an outer PUL layer to hold in wetness. Happy Heinys Trainers have been child tested and last 12+ hours overnight with absolutely no wicking for most children. Happy Heinys® Trainers are available in a variety of solid colors. They have a 100% poly laminated outer layer and work wonderfully for potty learners who still need protection overnight.
