Like our
@lanejudy said, any product that will help with urinary incontinence is going to allow some (or all) of the urine to "wash" out in the pool, regardless of if it's reusable or disposable.
There is a company call
Lil Helper that sells
washable/reusable pads that work for everyone. They started off selling diapers, then menstrual products, and then someone used the menstrual pads for incontinence, and here we are. I have personally used their products and find them to be very well made, and easy to care for. Simply follow their directions for care.
