Incontinence pads and guards protect against urinary leaks while still allowing you to wear traditional underwear. These products do not have full coverage on the front or back like diapers do. This makes them less bulky and more discreet under clothing. However, they can still absorb a large amount of liquid. Many incontinence pads have an adhesive strip on the bottom that helps keep it in place. Guards are especially designed for men and have a tapered shape that mainly provides coverage on the front of the body.
Booster pads are meant to be worn on top of a traditional diaper for extra absorbency. They do not have any adhesive on the bottom, which means that the diaper will not be torn when the booster needs to be removed. Booster pads prevent you from having to replace the whole diaper and can be changed out when needed. They can be especially helpful for caregivers.
