If you are very tall (over 6 feet(183cm) or sleep on your side you may have experienced the back of a diaper becoming exposed to your outer clothing or bedding resulting in embarrassments or a major laundry task. We extend the height of our regular cut plastic pants to give the extra coverage you need. Great for traveling too! Our Hi-Back pants are ideal over very thick diapers and for heavy people who need the extra fullness. FIT TIP: Hi-Back Styles are very full. If you wear with disposable diapers buy the smallest size that includes you waist/hip and leg measurements on our size chart for best fit. Please measure and use our size chart before ordering.
