The vented Afex leg bag is double sealed for increased protection and durability. A specialized membrane integrated into the vented collection bag allows air to vent out while liquid stays in. Our proprietary backflow valve ensures liquid stays in the bag during movement and activity. The secure drain clamp allows users to easily empty the bag at their convenience. The Afex leg bag is designed for use with the Afex Extension Tube Assembly for easy and rapid connect or disconnect of the collection bag.
