These bladder control pads quickly absorb and lock in large amounts of urine. The super-absorbent polymer disperses the fluid to insure dryness and prevent embarrassing overflow. These pads are designed much differently from sanitary pads, which are made to hold slow flowing menses. Urine is usually released quickly and in large amounts, which is why this super-absorbent polymer works so well. The cloth-like facing is soft and comfortable next to the skin.
