Attends Supersorb Advanced Underpads feature a Dry-Lock absorbent core which moves fluid away from the skin to help maintain skin health and wellness. Their soft, cloth-like topsheet provides added comfort while their leakage guard layer protects bed linens from wetness and helps reduce laundry volume, and their strong, breathable backsheet keeps these underpads in place without rolling or bunching and allows for their use on low-airflow mattresses. Plus, their odor-blocking properties help maintain a healthy environment.
