The Extra and Maxi absorbency have a waterproof backing and sticky strip.
The Standard Plus and the Standard Maxi absorbency contain no waterproof backing, meaning that when they are full, urine can seep all the way through.
These Classic Rectangular pads with a waterproof backing can be used with your own underwear or mesh pants.
Use in your own underwear by attaching with the sticky strip. Rustle-free waterproof backing.
Absorbency: 600 to 1250ml.
