Maxi Care Underpads are ideal for overnight use. These extra-large underpads provide protection from very heavy incontinence. Maxi Care™ Disposable Underpads feature a spunbond non-woven topsheet that allows fluid to pass quickly into the core where the super-absorbent polymer draws fluid away from skin and neutralizes odors. An embossed, extra-strong, moisture-proof backing protects against leakage and resists melting.
