SenSura® Mio features an elastic barrier designed to provide a secure and comfortable fit to real body shapes - including scars skin folds and hernias. Unlike standard pouches the pouch material is a water-resistant neutral gray textile designed to feel more like clothing and be discreet under all clothing colors. A built-in full-circle filter is designed to reduce clogging allowing the filter to express and deodorize gas without causing the pouch to expand like a balloon.
