Coloplast SenSura Mio Flex - Drainable 2-Piece Midi Opaque Ostomy Bag has an inspection window so you can monitor stomal output. The full circle filter is surrounded by a pre-filter that helps to trap stool and moisture before it reaches the filter while still allowing air and gas to escape. The full circle filter cuts down on clogs so the filter lasts longer and works better. The EasiClose wide outlet makes draining the pouch easier while still making sure the pouch closes securely. This ostomy bag is sold in a box of 10 and is compatible with Sensura Mio elastic adhesive barriers color coded "yellow". Coloplast SenSura Mio Flex is made with a comfortable fabric like material that dries quickly. The discreet gray color of the pouch is less visible under clothing.
