Medline Protection Plus Undergarments have a very thin design. They also contain an absorbent core that keeps patients dry and in control of their moderate flow. The new super absorbent polymer material maintains dryness and improves skin care. Extra wide belts (adjustable) are standard for these undergarments. Each case contains 4 bags of 30 undergarments. For each 30 undergarments, there is a extra wide belt. There is also an option to buy 25 belts which are sold separately (below under Product Accessories).
