The number of pieces refers to whether the system is a one-piece or two-piece design. Two-piece systems, like those in this category, allow you to change the pouch without removing the skin barrier, which can reduce skin irritation and provide greater flexibility. Users often prefer two-piece systems for their ease of use and ability to swap pouches as needed. The 401541, 401538, and 401540 all feature a two-piece design, offering flexibility and skin protection. Since all the available products are two-piece, you can enjoy these advantages across the entire line.
